摘要
PBAT是一种受欢迎的生物降解塑料,具有良好的延展性和优良的柔韧性,但PBAT的强度不高,导致其适用范围受到限制。为提高PBAT的强度,需对其进行改性。文章主要从共混与共聚方面综述了PBAT材料改性的研究进展,对PBAT与可生物降解聚合物、无机粒子、天然高分子等进行熔融共混改性以及PBAT聚合改性进行总结。未来,共混改性中应进一步提升改性填料与基体的相容性,共聚改性应通过聚合物链结构设计,调控刚性、柔性基团比例与分布以及聚合物链拓扑结构,提升PBAT的强度。研究为制备高强度PBAT复合材料提供思路。
PBAT is a popular biodegradable plastic,which has good ductility and flexibility,but the strength of PBAT is not high,which leads to the limitation of its application.In order to improve the strength of PBAT,it is necessary to modify it.In this paper,the research progress of PBAT modification was reviewed from the aspects of blending and polymerization.The melt blending modification of PBAT with biodegradable polymers,inorganic particles,and natural polymers,and the polymerization modification of PBAT were summarized.In the future,the compatibility between the modified filler and the matrix should be further improved in the blending modification.The polymerization modification should be designed through the polymer chain structure to control the proportion and distribution of rigid and flexible groups and the topology of the polymer chain,so as to improve the strength of PBAT.The research provides ideas for preparing high strength PBAT composites.
