摘　　要：通过化学氧化法合成聚苯胺,并利用原位聚合法将聚苯胺(PAN)包覆在碳微球(CMSs)上,采用熔融共混法制得阻燃聚苯胺包覆碳微球/聚对苯二甲酸乙二醇酯复合材料(CMSs-PAN/PET)。采用扫描电镜、红外光谱仪、热重和氧指数仪等,对其形貌结构、分散性、热稳定性能、阻燃性能和力学性能进行了分析和研究。结果表明,聚苯胺包覆后的CMSsPAN与原始CMSs相比,在PET基体中的分散性得到提高,CMSs-PAN/PET的拉伸强度比CMSs/PET提高了28.1%;与纯PET相比,CMSs-PAN/PET复合材料的热稳定性明显提高,其极限氧指数达到32.1,提高了10.4。Polyaniline( PAN) was synthesised by chemical oxidation,and coated on the carbon microspheres( CMSs) by in-situ polymerization. The CMSs-PAN/polyethylene terephthalate( PET) composite materials were prepared by melt blending. The morphologic structures,dispersion,thermal stability,flame retardant properties and mechanical properties of CMSs-PAN/PET materials were characterized by SEM,IR spectra,TG and oxygen index tester.The results show that the CMSs coated with polyaniline have better dispersion than the original CMSs in the PET matrix,and the tensile strength of CMSs-PAN/PET is increased by 28. 1% than that of CMSs/PET; compared with the pure PET,the thermal stability of CMSs-PAN composites is increased obviously; and the limiting oxygen index of CMSs-PAN composites is increased by 10. 4 and reaches 32. 1.
