"White pollution" causes serious harm to the environment,but people's lives are inseparable from plastic products.Degradable materials can greatly reduce the harm of plastic products to the environment.Polylactic acid(PLA)and poly-butylene terephthalate adipate(PBAT)are degradable materials,and their properties can be complementary,but their compatibility is poor,in order to large-scale use,it is necessary to modify the blend material.The research status of modification of PLA/PBAT blend films at home and abroad is reviewed in this paper.
