淀粉基可降解塑料研究进展

Research Progress of Starch-based Biodegradable Plastics

可降解塑料代替传统非降解塑料是国内外研究者们的研究热点。作为生物降解材料的淀粉易于获取,来源广泛,价格低廉,且极易被微生物分解,但是淀粉本身的特性使其应用受限,常常需与其他高分子材料进行复合。本文综述了目前淀粉基可降解塑料的研究进展,包括可降解塑料的分类,淀粉基可降解塑料定义,化学改性和合成全生物降解塑料。

With the introduction of biodegradable plastic Policy, biodegradable plastic instead of traditional non-biodegradable plastic has become a major focus of research by researchers at home and abroad. Compared with other natural macromolecules, starch is more easily obtained as a biodegradable material with wide sources and low price, and is easily decomposed by microorganisms. However, the application of starch itself is limited, and it needs to be compounded with other macromolecules in case of deficiency. In this paper, the research Progress of starch based degradable plastics was reviewed, including the classification of degradable plastics and starch based degradable plastics, chemical modification of starch, synthesis of whole biodegradable plastics.
