AB  - Hybrid geopolymers represent a new class of composite materials formed by incorporating organic polymer into a geopolymer matrix. The properties of hybrid geopolymer depend on the addition of organic phase and the starting raw material composition (concentration of NaOH in alkaline activator, Si/Al mass ratio and solid/liquid mass ratio). In addition to these relevant parameters, this paper examines the synthesis conditions of these materials through the influence of the type, amount and manner of adding organic modifiers (commercial epoxy resins and 3- (methoxyl) propyl methacrylates) on forming the structure with significantly reduced pore distribution and decreased pore size, which exhibits good mechanical properties. The purpose of this research is to define the optimal conditions of the hybrid geopolymers' synthesis through the examination of relevant parameters. Expected improvement of mechanical properties was confirmed through values of compressive stength. Characterization of hybrid geopolymer composities was performed by XRD analysis, DRIFT spectroscopy and SEM analysis.

AB  - There is potential use of red mud for synthesis of inorganic polymeric materials through a geopolymerization process as an alternative in the sectors of construction and building materials. By introducing of inorganic and organic modificators of microstructure (calcium hydroxide, bifunctional epoxy resins, or various types of alkoxylanes) during the geopolymer synthesis the enhanced values of ductility and strength can be obtained. Research was performed on alumosilicate material (red mud and metakaolin) and alkali activator raw mixture with defined quantity of modificator. The best sinthesys conditions were identified. Post-synthesis curing also play important role in obtaining of good-performing geopolymers. Characteristics of geopolymers were defined by measuring of compressive strength, N2-physisorption, as well as by SEM analysis, X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). In addition the lower value of zeta potential was identified as the assisting factor for the specific structure domains formation (within the certain range of pH) accompanied by the high compressive strength.

AB  - Effects of the hot pressing parameters on the designing of structures and properties of hydroxyapatite/poly-L-lactide (HAp/PLLA) biocomposite blocks have been studied. Interdependences of temperature, pressure and time of hot pressing and the density, compressive strength, elasticity modulus were defined. Microstructures of the fracture surfaces were observed by scanning electron microscopy (SEM). A wide spectrum of block properties such as relative density of 86.2-99.6%, compressive strength of 38.2-139.0 MPa and elasticity modulus of 1.9-10.0 GPa was obtained by varying the hot pressing parameters.
