摘　　要：通过文献调研梳理成果,综述植物纤维增强聚乳酸(PLA)复合材料研究进展,包括植物纤维的特性、制备方法及性能改进;剖析现存挑战并规划未来方向。研究显示,竹纤维、麻纤维等增强了PLA的力学性能和热稳定性,同时保持其可降解性,但纤维与基体界面结合力不足及分散性差仍是主要挑战。通过硅烷化、等离子体处理等改性技术,以及纳米技术的应用,显著改善了复合材料的综合性能。The research progress on plant fiber-reinforced polylactic acid(PLA)composites were reviewed,the existing challenges were analyzed,and future directions were outlined.The review encompasses the characteristics of plant fibers,preparation methods,and performance enhancements.It demonstrates that plant fibers such as bamboo and hemp significantly improve the mechanical properties and thermal stability of PLA while retaining its biodegradability.However,challenges persist,including insufficient inter-facial adhesion between fibers and the matrix and poor fiber dispersion.Advanced modification techniques,such as silanization,plas-ma treatment,and the incorporation of nanotechnology,have shown considerable improvements in the overall performance of these composites.
