可降解聚乳酸复合材料研究进展

Research progress in degradation characteristics of poly(lactic acid)composites

对聚乳酸(PLA)复合材料的生物降解性能进行综述,总结PLA与有机物(如木质素、纤维素等)、无机物(如碳酸钙、纳米银颗粒等)复合后力学性能、热性能、生物相容性、抗菌性的变化及在不同环境条件下生物降解速率的变化,梳理了PLA复合材料结构、组成与降解性能的相互关系,对降解性能可控的PLA复合材料应用前景进行了展望。

This paper reviewed the biodegradation performance of poly(lactic acid)composites and summarized the variation trends in their mechanical properties,thermal properties,biocompatibility,antibacterial properties,and biodegradation rate under different environmental conditions after compounded with organic substances such as lignin,cellulose,etc. and inorganic substances such as calcium carbonate,nano silver particles,etc. Furthermore,the material structures of polylactic acid composites and the relationship between the compositions and degradation properties were discussed,and the application prospect of poly(lactic acid)composites with controllable degradation properties was prospected.
