摘　　要：先用酸氧化法修饰碳微球(CMSs)的表面,再用化学合成法将苯胺(An)接枝在CMSs上制备CMSs-An复合物,最后用熔融共混法制备了CMSs-An/PET复合材料。采用扫描电镜(SEM)、红外光谱仪(FTIR)、热重(TG)、氧指数仪和垂直燃烧仪等手段对其形貌结构、分散性、热稳定性能、阻燃性能和力学性能进行了表征。结果表明,与原始CMSs相比,苯胺修饰后的CMSs-An在PET基体中的分散性提高了,使CMSs-An/PET的抗拉强度比CMSs/PET提高了20.8%;与纯PET相比,CMSsAn/PET复合材料的热稳定性明显提高,其极限氧指数提高了7.5达到29.2,垂直燃烧级别由V-2级上升到V-0级。Carbon microspheres(CMSs) were surface modified by the acid oxidation method and then grafted with aniline(An) by chemical synthesis to prepare compound CMSs-An. The CMSs-An/PET composite materials were prepared by melt blending CMSs- An and polyethylene glycol terephthalate(PET). The morphology, dispersiveness, thermal stability, flame retardant property and mechanical property of CMSs-An/PET materials were characterized by SEM, IR spectra, TG, oxygen index tester and vertical burning apparatus. The results show that, the aniline modified CMSs have better dispersiveness than that of the original CMSs in the PET matrix, and the tensile strength of CMSs-An/PET is 20.8% higher than that of CMSs/PET; in comparison with the pure PET, the CMSs-An/PET composite exhibits better performance: its thermal stability increased, limiting oxygen index increased by 7.5 and reached to29.2, and vertical burning grades increased from V- 2 level to V- 0 level according to the national standards.
