Treść
The paper presents research on degree of bioactivity of nanometric ceramic particles used as a nanofiller in nanocomposite materials based on polymers. The nanoperticles used in our examination were: different bioceramics powders such as: hydroxyapatite (HAp), β-phosphate (V) calcium (βTCP), silica (SiO2) and bioglass (BG). Based on ζ-potential measurements dynamics of processes occurring on the surface of nanoparticles in stimulated body fluid (SBF) was determined and it confirmed possibility of apatite formation. This study showed predominance of bioglass over other bioceramic materials, Bioglass nanoparticles were the most bioactive ones. In the end of the experiment the bioacermic particles were used as a nanofiller of poli-L/DL-lactide (PLDLA) matrix composites. The composite materials were prepared by casting from solution. Bioactivity tests were performed in simulated body fluid (artificial plasma of various ions concentration, and SBF 2SBF). Based on surface microstructure observed in the SEM (EDS) analysis were confirmed the degree of bioactivity of various materials depending on the type nanofiller.
