摘要

由于相对较高的价格、较慢的结晶速率、较弱的力学性能、较差的热稳定性、较窄的加工窗口和较慢的生物降解速率等自身的弱点

生物降解高分子材料并未如通用高分子材料一样得到广泛应用

制备以生物降解高分子为基体的纳米复合材料是有效的改性方法之一。本文结合作者近年来在生物降解高分子改性领域中的工作

对以笼型倍半硅氧烷(POSS)作为纳米填料改性左旋聚乳酸(PLLA)和聚ε-己内酯(PCL)的研究进行简单综述

POSS可有效提高PLLA和PCL基体的结晶速率和力学性能

并促进了聚合物基体的水解过程。

Abstract

The wider practical application of biodegradable polymers has been restricted because of their disadvantages

such as high cost

slow crystallization

slow degradation rate

poor mechanical properties

and thermal instability. The fabrication of biodegradable polymer nanocomposites is one of the most effective methods to modify biodegradable polymers. Based on the recent studies on the modification of biodegradable polymers in our lab

this review summarizes the recent progress of poly(L-lactic acid) (PLLA) and poly (ε-caprolactone) (PCL) based nanocomposites by incorporating polyhedral oligomeric silsesquioxanes (POSS) with different functional groups as nanofillers. It has been found that POSS can enhance the crystallization and hydrolytic degradation processes and improve the mechanical properties of both PLLA and PCL effectively.
