The phase composition and unit cell parameters were determined for composites based on polylactide and hydroxyapatite with the polylactide/hydroxyapatite weight ratios of 90/10, 80/20, 70/30, and 60/40. As the polylactide content of the composites is increased, they become less hydrophilic, and the surface energy σS-G increases from 29.13 to 74.35 mJ m–2. The sample with the component weight ratio of 70/30 is characterized by the maximal roughness, and the Ca2+ and Mg2+ ions from simulated body fluid are actively adsorbed onto its surface, as proved by SEM examination of the composites. |
