摘　　要：由于生物基聚乳酸(PLA)材料具有优异的力学性能和良好的生物可降解性,其是目前最具有发展潜力的生物可降解材料之一。但是,其脆性较大,限制了聚乳酸材料的应用范围。因此,通过介绍滑石粉(Talc)物理改性聚乳酸材料的进展,总结了通过细化滑石粉的粒径及其表面功能化处理等改性方法提高滑石粉对聚乳酸(PLA)材料的增强作用和成核效应。详细阐述了滑石粉(Talc)及其与增塑剂、弹性体、生物可降解材料、植物纤维等材料增韧改性PLA材料的研究进展。利用Talc的增强和成核效应及韧性聚合物的增韧作用,充分发挥多组分之间的协同效应,是未来制备高性能的聚乳酸材料的主要途径和研究方向。Biobased polylactic acid(PLA)material is one of the most potential biodegradable materials due to its excellent mechanical properties and good biodegradability.However,PLA inherent brittleness limits its the wide application.The progress of physical modification of poly(lactic acid)materials with Talc was introduced.The enhancement and nucleation effect of Talc on PLA materials were summarized by refining particle size and surface functionalization treatment of Talc.The research on toughening and modification of PLA materials by Talc,and its combined with plasticizer,elastomer,biodegradable material,plant fiber and other materials was described in detail.With the enhancement and nucleation effect of Talc and the toughening effect of ductile polymer,it is the main way and research direction for the preparation of high-performance PLA materials in the future to exert the synergistic effect among multi-components.
