Research Progress of PBAT Enhancement Modification
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.
