可生物降解塑料PBAT共混改性研究进展

Progress of Blending Modification of Biodegradable Plastic PBAT

可生物降解塑料聚己二酸对苯二甲酸丁二酯(PBAT)的改性是降低其成本、提高性能的重要方法。主要综述了近十几年来国内外PBAT的共混改性研究进展,主要包括聚乳酸、聚碳酸亚丙酯、聚丁二酸丁二醇酯、聚羟基丁酸戊酯、聚乙醇酸、聚乙烯醇缩丁醛等可降解高分子与PBAT共混改性,玉米淀粉、纤维素和木质素等有机填料与PBAT共混改性,以及碳酸钙、蒙脱土等无机填料与PBAT共混改性,并对其发展作出总结与展望,旨在为开发新型高效的PBAT复合材料提供指导意义。

Modification of poly(butylene adipate terephthalate)(PBAT)is an important method for lowering the production cost and improving properties.The research progress of blending modification of PBAT in the past ten years,mainly including blending with biodegradable polymers such as polylactic acid,poly(propylene carbonate),polybutylene succinate,polyhydroxybutyrate valerate,polyglycolic acid and polyvinyl butyral were mainly summarized,blending with organic fillers such as corn starch,cellulose and lignin,and blending with inorganic fillers such as calcium carbonate and montmorillonite were summarized.The prospects its development were also summarized.The objective is to provide guidance for the development of new and efficient PBAT composite materials.
