摘　　要：大量传统的地膜聚乙烯(PE)膜在提高农作物产量的同时,也带来了严重的环境污染和生态安全问题。为解决这些问题,开发、设计和使用新型生物可降解地膜迫在眉睫。脂肪族—芳香族类共聚物是一种新型的生物可降解材料,兼具脂肪族聚酯优异的降解性能和芳香族聚酯的良好力学性能。其中,聚己二酸/对苯二甲酸丁二酯(PBAT)因其力学性能与低密度聚乙烯(LDPE)相当而备受青睐。因此,就PBAT基地膜的力学性能、光稳定性、水蒸气渗透性、抑草性以及生物降解性等方面做一概述,最后对PBAT地膜的未来研究做出展望。A large number of traditional polyethylene(PE)films not only increase crop yield,but also bring serious environmental pollution and ecological security problems.In order to solve these problems,it is urgent to develop,design and use new biodegradable film.Aliphatic aromatic copolymer is a new type of biodegradable material,which has excellent degradation properties of aliphatic polyester and good mechanical properties of aromatic polyester.Among them,poly(adipic acid/butylene terephthalate)(PBAT)is popular because its mechanical properties are similar to those of low density polyethylene(LDPE).Therefore,in this paper,the mechanical properties,photostability,water vapor permeability,grass inhibition and biodegradability of PBAT based membrane were summarized.Finally,the future research of PBAT based membrane was prospected.
