摘　　要：文章综述了近年来纳米材料改性聚对苯二甲酸乙二醇酯(PET)的研究现状,主要介绍PET复合材料的改性方法,从常见的纳米材料改性和二维纳米材料改性两个方面综述了填料对PET复合材料的力学性能、结晶性能、热稳定性、热传递性能及阻隔性能提升的效果。文章指出纳米填料在基体中均匀分散,有利于降低结晶活化能,增加PET链段的自由体积,从而提高PET的结晶性能。最后,文章对二维纳米材料在PET改性中应用进行展望。The research status of polyethylene terephthalate(PET) modified by nano-materials in recent years is reviewed.The modification methods of PET composites were introduced.The effects of fillers on the improvement of mechanical properties,crystallization properties,thermal stability,heat transfer properties,and barrier properties of PET composites were summarized from two aspects of common nano-material modification and two-dimensional nanomaterial modification.It is pointed out that the homogeneous dispersion of nano-fillers in the matrix is beneficial to reduce the activation energy of crystallization and increase the free volume of PET segments,thus improving the crystallization properties of PET.The application of two-dimensional nano-materials in PET modification is prospected.
