增韧改性聚乳酸基生物降解材料研究进展
Research Progress in Toughening Modified Polylactic Acid Based Biodegradable Materials
摘要
Abstract
Polylactic acid(PLA)has good mechanical properties and biodegradability,which are of great significance for sustainable development and low-carbon environmental protection.However,PLA has high brittleness and poor toughness,which limit its wide application.Considering that the use of petroleum-based materials to toughen PLA will reduce its degradability,PLA can be toughened by non-degradable or renewable materials.The research progress of toughening modification methods of PLA-based biodegradable materials is reviewed,mainly from the perspectives of chemical modification,physical modification,and composite modification.The definition of toughening methods,the advantages and disadvantages of research at home and abroad,and the improvement methods are summarized,providing a reference for the toughening modification of biodegradable PLA.It is pointed out that the future research direction of toughening modification of PLA-based biodegradable materials is to develop green and environmentally friendly modification methods,reduce costs,and search for monomers with good compatibility and biodegradability.关键词
