天然高分子改善聚乙烯生物降解性的研究现状

The current research of the natutal polymer to improve the biodegradation of polyethylene

聚乙烯是一种应用十分广泛的高分子材料,但是降解速度十分缓慢,导致了严重的环境污染问题。本文论述了天然高分子改性聚乙烯的研究进展,其中主要介绍了淀粉、壳寡糖和壳聚糖。

Polyethylene was a kind of widely used polymer material. The degradation speed of polyethylene was very slow and caused the problems of serious environmental pollution. The research progress of natural polymers modified polyethylene were reviewed,and the starch,chitosan and chitosan oligosaccharide were mainly reviewed.
