可降解材料增韧聚乳酸的研究进展
Research Progress of Polylactic Acid Toughened by Degradable Materials
摘要
Abstract
Polylactic acid(PLA)is a biodegradable,renewable,and high-performance biopolyester.However,its inherent brittleness restricts its broader application,making toughening modification a hot spot of its research.The use of non-biodegradable materials will weaken the degradation performance of PLA,so the adoption of biodegradable materials has become the preferred strategy for toughening PLA.The paper outlines the structural characteristics and current development of PLA,summarizes the research progress of using biodegradable materials to prepare fully biodegradable PLA composites at home and abroad,focuses on the advantages,disadvantages and improvement methods of biodegradable plastics[polybutylene adipate/terephthalate(PBAT),polybutylene succinate(PBS),polycaprolactone(PCL),polyhydroxybutyrate(PHB)]and natural polymers(natural fiber,starch,vegetable oil)to toughen PLA,and points out the problems faced in toughening and modifying PLA.It is pointed out that the enhancement of the interfacial compatibility between the multiphase systems and the overall improvement of the comprehensive performance of the materials are the important directions for future research on fully degradable materials.关键词
