AB  - Biphasic calcium phosphate/poly-L-lactide granules of 150-200 mu m sizes were subjected to high-energy mechanical milling in a planetary ball mill for up to 480 minutes. Characterization of the material obtained was carried out using X-ray diffraction (XRD), differential scanning calorimetry (DSC), environmentally scanning electronic microscopy (ESEM), transmission electron microscopy (TEM) and infrared spectroscopy (IR). These techniques confirmed that mechanical milling induced significant changes in the biocomposite structure and properties. The most significant changes are reduction of the HAp crystallites size from 99.8 to 26.7 nm and beta-TCP from 97.3 to 29.6, as well as crystallinity of PLLA phases. Homogeneous phase distribution (arrangement) is obtained by extending the duration of mechanical milling.

AB  - Promena strukture i osobina biokompozitnog materijala HAp/PLLA tokom mehano­hemijskog tretmana predmet su analize u ovom radu.

AB  - Mechanochemically treated hydroxyapatite/poly-L-lactide (HAp/PLLA) composite biomaterial undergoes significant changes in structure and properties. These were the subject of the analysis presented in this paper. HAp/PLLA mixture was evaporated in vacuum and then subjected to dry milling in a planetary ball mill for 480 minutes. Characterization of the material obtained was carried out using X-ray diffraction (XRD), differential scanning calorimetry (DSC), scanning electronic microscopy (SEM), transmission electronic microscopy (TEM) and infrared spectroscopy (IR). These techniques confirmed that mechanochemical treatment induces changes in the composite biomaterial. The most significant changes are reduction of PLLA crystallinity and size of HAp crystalites.
