全生物降解高抗冲PLA/PBAT复合材料的制备与性能
Preparation and Properties of Fully Biodegradable High Impact PLA/PBAT Composites
摘要
Abstract
Poly(butyleneadipate-co-terephthalate)(PBAT)was used to toughen poly(lactic acid)(PLA),and a fully biodegradable high impact PLA/PBAT composite was prepared.To improve the interface compatibility between PBAT and PLA,PBAT grafted glycidyl methacrylate(GMA)(PBAT-GMA)compatibilizer was prepared by the melt grafting method.The effect of the mass fraction of compatibilizer on the properties of PLA/PBAT composite was studied.The results show that with the increase of PBAT-GMA mass fraction,the impact strength of the composites is significantly improved.When the PBAT-GMA mass fraction is 30%,the impact strength of the composites reaches 64.8 kJ/m2,and the elongation at break is 289.9%;the compatibilizing mechanism is the epoxy groups on PBAT-GMA can react with the end groups of PLA,which effectively improves the interfacial compatibility between PLA and PBAT.关键词
