共混改性调控聚乳酸结晶及力学性能的研究进展
Research progress in blending modification for regulating crystallization and mechanical properties of poly(lactic acid)
摘要
Abstract
This paper addresses the limitations in crystallization behavior and mechanical properties of polylactic acid(PLA)stemming from its inherent molecular chain structure.Recent advancements in blending modification strategies for enhancing the crystallization and mechanical performance of PLA,as reported in domestic and international studies,are comprehensively reviewed.Key approaches include elastomer modification,polymer alloy blending,inorganic mate-rial reinforcement,nanoparticle incorporation,bio-based material integration,nucleating agent optimization,chain ex-tender-based modification,and synergistic multi-component systems.To advance this field,prioritizing the use of biode-gradable or bio-based fillers in PLA blends was proposed while improving interfacial compatibility.Furthermore,future research should focus on developing low-cost,PLA-compatible modifiers and eco-friendly compound systems.Such in-novations represent a critical pathway to achieving high-performance PLA materials through sustainable blending modifi-cation techniques.关键词
