以聚乳酸类生物降解高分子为基体、以无机钙质成分(羟基磷灰石、磷酸钙、珊瑚、珍珠层等)为增强材料的聚乳酸类复合材料,具有良好的生物相容性,在骨修复领域有重要的应用。本文介绍了其研究近况,指出使用新型的复合工艺、采用纳米增强材料和开发新型增强材料是聚乳酸类复合材料的发展趋势。
Polylactic acid biodegradable polymer as the matrix, with inorganic calcareous ingredients (hydroxyapatite, calcium phosphate, coral, nacre, etc.) as a reinforcing material of polylactic acid composite materials, has good biocompatibility, in the There are important applications in the field of bone repair. In this paper, the current situation of its research is introduced. It is pointed out that the use of new composite technology, the use of nano-reinforcing materials and the development of new reinforcing materials are the trends of polylactic acid composites.
