AB  - Recent advances in material technologies have resulted in the preparation of novel polymer/clay composites with improved thermal, mechanical, optoelectronic/ magnetic properties and increased biodegradability [1]. In this study, six samples of poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) (PGME) nanocomposites with organically-modified montmorillonite clay Cloisite 30B® (C30B), were prepared via suspension copolymerization. In order to obtain nanocomposites with fine spherical beads of regular shape and satisfying thermal stability the optimization of the synthesis conditions was performed. Firstly, the influence of the poly(N-vinyl pyrrolidone) (PVP) quantity in the aqueous phase was varied (1, 3 and 5 wt.%) at a constant stirring rate of 250 rpm and constant clay content C30B (10 wt.%). In the second phase of the optimization of the preparation, samples with a constant composition of the composite reaction mixture (5 wt.% PVP and 10 wt.% C30B) at a stirring rate of 250, 325 and 400 rpm, were prepared. According to the obtained results, it was concluded that the optimal conditions for preparation of these composites are 5 wt.% of PVP and 400 rpm. The prepared nanocomposites were characterized with Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA) in air. The structure of the prepared nanocomposites was confirmed with FTIR spectroscopy. According to the obtained SEM microphotographs the fine spherical beads, with desired size and homogeneous morphology, were prepared. Furthermore, SEM analysis was also showed that clay nanoparticles are homogeneously dispersed both inside surface and cross-section area. The incorporation of C30B clay increased the thermal stability of the prepared polymer/clay nanocomposites in comparison to the pure PGME copolymer.

AB  - A novel method combining a traditional immersion precipitation process for making membranes with photopolymerization and crosslinking of functional monomers included in the casting solution was used to prepare asymmetric polyethersulfone membranes with submicron particles incorporating glycidyl methacrylate copolymer. In order to introduce sulfonic groups epoxide rings of glycidyl methacrylate were opened using two methods. The first method was functionalization with sodium sulfite, and the second method was functionalization with sulfuric acid and then grafting with 2-acrylamido-2-methylpropane sulfonic acid. Obtained membranes were characterized using infrared spectroscopy, conductometric titration and water permeability measurements. Scanning electron microscopy and atomic force microscopy were used to investigate the surface morphology and topology of membrane. Dynamic adsorption of Rhodamine B as a model dye was used to demonstrate suitability of these novel membranes for membrane adsorption since the adsorption capacity for dye cations was much better for both functionalized membrane with sodium sulfite and grafted membrane with 2-acrylamido-2-methylpropane sulfonic acid compared to the nonfunctionalized membrane.

AB  - Pronalazak se odnosi na asimetričnu poroznu membranu sa epoksidnim prstenovima. Ovakva membrana se može dobiti pojednostavljenim postupkom koji izbegava mnoge dodatne operacije u cilju funkcionalizacije postojećih asimetričnih membrana. Po tom postupku homogeni rastvor za polimerizaciju koji obuhvata reaktivnu komponentu sa epoksidnim prstenovima, umreživač, staklasti polimer i rastvarač, oblikuje se u određenu formu, izloži izvoru zračenja u cilju polimerizacije i umrežavanja reaktivnih komponenata i potopi u koagulaciono kupatilo u kome se pomenuta membrana konačno formira. Epoksidni prstenovi se jednostavnim hemijskim reakcijama mogu konvertovati u željene funkcionalne grupe i takve membrane se mogu koristiti za čitav niz separacionih procesa, kao što su ultrafiltracija, membranska adsorpcija za hemijske ili biohemijske primene, ili u sklopu senzora zasnovanih na membranama i tankim filmovima.
AB  - The invention herewith described refers to the asymmetric porous membrane with epoxide rings. Such membrane can be prepared using a simplified method which omits many additional steps carried out in order to functionalize existing asymmetric membranes. According to this method a homogeneous polymerizable solution comprising a reactive component with epoxide rings, a crosslinker, a glassy polymer, and a solvent, is formed into a shaped article, exposed to a source of irradiation to polymerize and crosslink the reactive components, and immersed into a coagulation bath to form said membrane.; Epoxide rings can be converted into desired functional groups using simple chemical reactions and such membranes can be utilized for a broad range of separation processes including ultrafiltration, membrane adsorption for chemical or biochemical applications, or in sensing devices based on membranes and thin films.

AB  - Polyethersulfone membranes with integrated negatively-charged hydrogel of crosslinked poly(acrylamido-2-methylpropane sulfonic acid) were prepared by a combination of a liquid phase inversion process with photopolymerization and crosslinking of functional monomers included in the casting solution. A designed experiment was conducted to select the optimal composition for preparing membranes with a sufficient degree of swelling and ion exchange capacity. Scanning electron microscopy images revealed an ultrafine hybrid structure with an interconnected network of submicron particles embedded within the microporous polyethersulfone support. An intramembrane diffusion model was used to describe kinetics of heavy metal sorption by these hydrogels and the calculated apparent diffusion coefficients were 2–3 times larger than in commercial ion-exchange resins. Equilibrium sorption of heavy metals was described using a semi-empirical Langmuir model.

AB  - Inverse gas chromatography at infinite dilution was applied to determine the thermodynamic interactions of poly(l-lactide) (PLLA) and the composite of biphasic calcium phosphate and PLLA (BCP/PLLA). The specific retention volumes, V0g , of 11 organic compounds of different chemical nature and polarity (non-polar, donor or acceptor) were determined in the temperature range of 308–378 K for PLLA and 308–398 K for BCP/PLLA. The weight fraction activity coefficients of test sorbates, Ω∞1 , and the Flory–Huggins interaction parameters, χ∞12 , were estimated and discussed in terms of interactions of the sorbates with PLLA and BCP/PLLA. Also, the partial molar free energy, ΔG∞1 , the partial molar heat of mixing, ΔH∞1 , the sorption molar free energy, ΔGS1 , the sorption enthalpy, ΔHS1 , and the sorption entropy, ΔSS1 , were analyzed. A different chromatographic behavior of the two investigated samples, PLLA and BCP/PLLA, was observed. The values of Ω∞1 indicated n-alkanes, diethyl ether, tetrahydrofurane (THF), cyclohexane, benzene, dioxane (except for 338 K), and ethyl acetate (EtAc) (except for 338 K) as non-solvents, and chloroform (CHCl3) as good solvent (except for 378 K) for PLLA. For BCP/PLLA, CHCl3, EtAc (for 378 K), dioxane (except for 378 K), and THF were indicated as good solvents.

AB  - Asymmetric polyethersulfone membranes with submicron particles comprising crosslinked poly(glycidyl methacrylate-co-2-acrylamido-2-methylpropane sulfonic acid) were prepared by a combination of a traditional liquid phase inversion process for making membranes with photopolymerization and crosslinking of functional monomers included in the casting solution. Scanning electron microscope images of the membrane cross-section revealed a hybrid structure with an interconnected network of submicron particles embedded within the porous polyethersulfone support. Permeation of toluidine blue solutions through non-functionalized membranes showed a dramatic effect of 2-acrylamido-2-methylpropane sulfonic acid concentration in the casting solution on the dynamic adsorption performance. The epoxide groups present in glycidyl methacrylate copolymer were transformed into amine functionalities by ring opening under alkaline conditions. Permeation of dilute Cu2+ solutions through functionalized membranes demonstrated that the plate height for some of these membranes was an order of magnitude smaller than for commercial particle-filled membranes used in solid phase extraction.

As the concentration of polymerizable monomers increased the original macrovoid structure was replaced by a hybrid morphology with microglobules typical of macroporous methacrylate adsorbers embedded within microporous structure with no significant effects on water permeability. The epoxide groups present in glycidyl methacrylate copolymer were transformed into amine functionalities by ring opening under alkaline conditions. Permeation of Orange G solution at low transmembrane pressures was used to demonstrate suitability of these novel membranes for membrane adsorption.

An experimental design measuring water content and ion-exchange capacity of these membranes was used to select the optimal membrane composition for the removal of Pb2+, Ni2+, and Cd2+ ions from aqueous solutions. The results demonstrated fast sorption kinetics and high capacity for the investigated metals.

AB  - Ultrafiltration (UF) membranes are currently used in industry for the concentration of proteins and other macromolecules. Performance of UF membranes is generally limited by a trade-off between permeability and selectivity [1]. However, electrically-charged ultrafiltration membranes can provide a dramatic improvement in ultrafiltration performance [2]. Novel UF membranes were made by combining traditional immersion precipitation process for making membranes with photopolymerization of the casting solution comprising polyethersulfone, glycidyl methacrylate and other reactive monomers. Negative charges were introduced either by initially using 2-acrylamido-2-methylpropane sulfonic acid as a reactive monomer, or were later created by epoxide ring opening of crosslinked glycidyl methacrylate. As shown in Fig. 1, selectivity of these membranes significantly improved as the concentration of negatively-charged groups in the membrane increased. The effects of membrane composition on the properties and separation performance of these novel UF membranes will be presented.

AB  - Polyethersulfone (PES) is frequently used for high-performance ultrafiltration membranes. Functionalization of PES membranes is required to introduce new groups for specific applications, such as affinity membranes for bioseparations [1]. Functionalization methods include bulk modification of PES material, blending of PES with another material, or surface modification of PES membranes [2]. In this work a novel method for introducing functional groups in asymmetric PES membranes is presented [3]. A cast film comprising PES, glycidyl methacrylate (GMA) and a common solvent was exposed to UV irradiation to form a gel of crosslinked polyGMA. The gel was then immersed in a water bath to create an asymmetric membrane with crosslinked polyGMA particles, as shown in Fig. 1. A simple treatment of these membranes with diethylene triamine was used to open the epoxide rings in polyGMA particles and introduce amine functional groups. The effects of monomer concentrations on the properties and separation performance of these novel membrane adsorbers will be presented.

AB  - Affinity-based devices utilizing plasmonic effects belong to the most sensitive chemical sensors. A membrane having a form which coincides with the distribution of surface electromagnetic waves coupled with collective oscillations of electron gas in the conductive part of the sensor represents an important building block for plasmonics. A way to boost selectivity of a plasmonic sensor is to functionalize such membrane and either to apply it on the sensor surface or even to use it as a stand-alone platform for sensing. In this work we considered a possibility to prepare multifunctional membranes for plasmonic sensing. In our experiments selectivity enhancement was achieved through the use of glycidyl methacrylate whose epoxy group is readily converted to a desired affinity group (e.g. amine, thiol, pyridine, dithiocarbamate) to preferently capture a targeted species. Further plasmonic functionalization was obtained by forming a thin hydrogel film through copolymerization of glycidyl methacrylate with mono- and multi-functional methacrylates and then incorporating silver nanoparticles within these nanocomposites. These plasmonic nanoparticles were produced either photochemically or by chemical reduction. Different schemes for plasmonic sensor selectivity enhancement using multifunctionalized glycidyl methacrylate membranes are considered.

AB  - We considered the possibility to fabricate multifunctional nanocomposite membranes as a platform for plasmonic metamaterials, simultaneously incorporating pores, built-in functional groups and active nanoparticles. To this purpose we combined lamination and inclusion of nanofillers into the membrane host. For the basic material we chose macroporous crosslinked copolymers based on glycidyl methacrylate (GMA). The epoxy group present in GMA molecule is readily transformed into various functional groups that further serve as affinity enhancers, ensuring the usability of the membranes as pre-concentrators of selected agents in plasmonic sensors. To form GMA-based membranes we used a recently proposed method combining the traditional immersion precipitation with photopolymerization and crosslinking of functional monomers. Further functionalization is obtained by in-situ formation of noble metal nanoparticles directly within the GMA host. In this way membranes with simultaneous plasmonic, adsorbent and catalytic functionality are obtained. We considered the use of the our structures for plasmonic chemical sensors where separator, pre-concentrator and binding agent are integrated with the plasmonic crystal, as well as for plasmonic enhancement of photocatalytic reactions in microreactors. Our approach gives a highly tailorable element compatible with microelectromechanical systems (MEMS) technologies and readily transferable across platforms.

This paper presents the synthesis of novel asymmetric polyethersulfone membranes containing an interpenetrating network of poly(glycidyl methacrylate) (PGMA). In order to improve the properties and application range of membranes, the epoxy groups from PGMA are converted to amine groups by ring opening under alkaline conditions. Membranes before and after functionalization are characterized by FTIR-ATR, elememtal analysis and water permeability.

Membrane-based plasmonic nanocomposites for chemical or biological sensing

AB  - One of the important applications of subwavelength plasmonic optics is sensing of chemical and biological analytes [1]. Plasmonic sensors are based on tuning of either propagating surface waves (surface plasmon polaritons, SPP) or nonpropagating (localized) ones. The adsorption of analyte modifies the surface refractive index, ensuring ultrahigh sensitivities that may exceed 10–8 refractive index units, i.e. 1 ng/cm2 (0.003 monolayer) [2]. For all plasmonic sensors it is of interest to enhance their selectivity, since their operation is based solely on refractive index sensing, i.e. different materials with similar refractive indexes cause similar outputs. In this work we propose the integration of active plasmonic part with separator (e.g. membrane or nanomembrane with nanopores) and ligand binding the targeted analyte into a single structure. This may be done by membrane nanocompositing [3], e.g. by lamination (Fig. 1a) or volume structuring/pore formation (Fig. 1b). At the same one may use built-in (nano)pores to augment the effective surface for adsorption and thus vastly increase the amount of adsorbate. For our work we chose macroporous crosslinked copolymers (MCP) which are readily formed into membranes and keep a permanent well-developed porous structure. Particularly we used glycidyl methacrylate (GMA)-based MCP. GMA has already been successfully used for heavy and precious metals adsorption and enzyme immobilization [4]. For the formation of membranes comprising GMA we selected a new method combining traditional immersion precipitation with photopolymerization and crosslinking of functional monomers [5]. Our approach may be extended to other types of chemical and bio sensors.

The adsorption of analyte modifies the surface refractive index, ensuring ultrahigh sensitivities that may exceed 10–8 refractive index units, i.e. 1 ng/cm2 (0.003 monolayer) [2]. For all plasmonic sensors it is of interest to enhance their selectivity, since their operation is based solely on refractive index sensing, i.e. different materials with similar refractive indexes cause similar outputs. In this work we propose the integration of active plasmonic part with separator (e.g. membrane or nanomembrane with nanopores) and ligand binding the targeted analyte into a single structure. This may be done by membrane nanocompositing [3], e.g. by lamination (Fig. 1a) or volume structuring/pore formation (Fig. 1b). At the same one may use built-in (nano)pores to augment the effective surface for adsorption and thus vastly increase the amount of adsorbate. For our work we chose macroporous crosslinked copolymers (MCP) which are readily formed into membranes and keep a permanent well-developed porous structure. Particularly we used glycidyl methacrylate (GMA)-based MCP. GMA has already been successfully used for heavy and precious metals adsorption and enzyme immobilization [4]. For the formation of membranes comprising GMA we selected a new method combining traditional immersion precipitation with photopolymerization and crosslinking of functional monomers [5]. Our approach may be extended to other types of chemical and bio sensors.

AB  - Bioresorbable barrier membranes have been widely used in dentistry and maxillofacial surgery. When the membranes are placed over bony defects and are closely adapted by the surrounding bone face, an environment that prevents invasion of competing non-osteogenetic cells from the overlying soft tissues can be created. The aim of the present study was to establish whether the production procedure of different polymeric and composite membranes affects their physicochemical properties. The physicochemical properties were examined by differential scanning calorimetry (DSC), scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS), inverse gas chromatography (lGC) and tensile strength test (TST). The surface microstructure, dependent on the processing parameters, was perforated with smaller or larger pores. The dispersive component of the free surface energy decreased by adding bicalcium phosphate (BCP) to the polymer and, consequently, non-polar interactions with the surroundings became preferential.
