摘　　要：近年来,为了解决不可降解塑料对环境造成的危害,关于生物降解塑料的研究越来越多。聚己二酸/对苯二甲酸丁二醇酯(PBAT)具有较好的生物降解性、延展性及断裂伸长率,同时还具有较好的耐热性及抗冲击性能,是目前最有发展前景、研究最广泛的可降解塑料。但是,其价格较高,降解周期较长。采用植物纤维与PBAT进行复合,并且,对其进行改性,可解决以上缺陷。综述了近年来植物纤维/PBAT复合材料的研究现状,重点介绍了采用不同的改性方法对植物纤维进行改性,改善PBAT复合材料的性能,改性方法包括化学改性、物理改性等及复合材料中的界面增容技术。另外,简要阐述了复合材料的相关性能。In recent years,research on biodegradable plastics has rapidly emerged to address a series of environmental hazards caused by non degradable plastics.Polyadipic acid/butylene terephthalate(PBAT)has good biodegradability,good ductility and elongation at break,as well as good heat resistance and impact resistance.It is currently the most promising and popular biodegradable plastic.But the price is relatively high and the degradation cycle is longer.The use of plant fibers combined with PBAT and their modification can overcome these shortcomings.This article reviews the research status of plant fiber/PBAT composite materials in recent years,focusing on various modification methods adopted to improve the relevant properties of composite materials,such as chemical modification,physical modification,and interface compatibilization technology in composite materials.The relevant properties of composite materials are briefly explained.
