摘　　要：综述了近年来共混技术在淀粉塑料中应用的研究现状及进展。以所共混聚合物组分的不同为主线,分为3大类共混体系,即淀粉与可降解聚合物,淀粉与不可降解聚合物,淀粉与可降解和不可降解聚合物三元体系。同时,从材料构效关系的基本原理出发,以共混体系的微观结构和宏观性能为侧重点,着重探讨了共混体系中各组分之间的相界面形态关系,组分之间的相容性,以及不同聚合物组成对共混体系的力学、吸水、加工成型、热及降解性能的影响,并对未来的发展趋势进行了展望。Research progress in recent years of the applications of blending technology in starch plastics is reviewed.Based on the different polymer component in the blend,the blends are divided into three categories,namely starch and biodegradable polymers;starch and non-degradable polymers;starch,biodegradable and non-degradable polymer ternary system.Meanwhile,according to the basic principles of the material structure-activity relationship,and focusing on the microstructure and macroscopic properties of the blends,the relationship of interface morphologies of the phases and compatibility of various components of the blends are analyzed.The effects of different composition on mechanical,water absorption,molding process,thermal and degradation properties of the blends are also studied.At last the future development trend of the blending technology in starch plastics is prospected.
