摘要

为了提高DL-聚乳酸(PDLLA) 的柔韧性

将10 ～ 20wt%不同比例的由本课题组自主合成的高分子量聚对二氧环己酮(PPDO) 加入到PDLLA 基体中

对共混物的微观两相形态、力学性能、热学性能和表面性质、降解性能等物化性质进行了研究。实验结果表明

PPDO 加入后

在PDLLA PPDO 共混物的柔韧性得到显著提高的同时

共混物表面亲水性相应提高

降解速率也随之加快。

Abstract

In this study

in order to improve the flexibility of poly (DL-lactide) (PDLLA)

a high molecular weight poly(dioxanone) (PPDO) with great flexibility was added in PDLLA matrix with different weight ratios.Hybrids were characterized in terms of phase structure (scanning electron microscopy)

thermal properties(differential canning calorimetry and dynamic mechanical analysis)

mechanical properties(tensile analysis)

surface properties(dynamic contact angle analysis) and degradability.As a result of the PPDO appended in

the flexibility of the PDLLA was significantly improved as well as the degradation speed of the blends.
