摘要
聚甲基乙撑碳酸酯(PPC)是由环氧丙烷与二氧化碳聚合制得的脂肪族聚酯,具有生物相容性、生物降解性和良好的韧性和延展性。由于纯PPC树脂存在拉伸强度和模量低、热稳定性差、价格贵等缺点,需要各种无机或有机材料对其进行共混改性。制备可完全生物降解的PPC共混复合材料已成为当前研究热点。本文介绍了近年来可以完全生物降解的PPC共混复合体系,综述了其最新研究进展。
Poly（propylene carbonate）（PPC） is a kind of aliphatic polycarbonate made from propylene epoxide and carbon dioxide. It exhibits good biocompatibility, biodegradability, toughness and ductility. Due to some disadvantages such as weak tensile strength and modulus, poor thermal stability and expensive, it needs various inorganic or organic materials to modify PPC. Recently, much attention has been paid to prepare completely biodegradable blends with PPC matrix. The completely biodegradable PPC blend system was introduced and the latest research progress were summarized.
