Promena strukture i osobina biokompozitnog materijala HAp/PLLA tokom mehanohemijskog tretmana predmet su analize u ovom radu. Smeša HAp/PLLA uparena je u vakuumu i zatim podvrgnuta suvom mlevenju u planetarnom mlinu do 480 minuta. Korišćene su rendgenostrukturna analiza (XRD), diferencijalna skanirajuća kalorimetrija (DSC), skenirajuća elektronska mikroskopija (SEM) transmisiona elektronska mikroskopija (TEM) i infracrvena spektroskopija (IR) za karakterizaciju dobijenog materijala. Na osnovu primenjenih analiza utvđen je uticaj mehanohemijskog tretmana na promene kompozitnog biomaterijala. U najvećoj meri dolazi do smanjenja kristaliničnosti poli-L-laktida(PLLA) i smanjenja veličine kristalita hidroksiapatita (HAp). Sa povećanjem vremena mehanohemijskog tretmana dobija se homogena raspodela faza.
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. Homogeneous phase arrangenment is obtained by extending the duration of mechanochemical treatment.
