为改善碳微球(CMSs)/碳纳米管(MWNTs)与聚对苯二甲酸乙二醇酯(PET)基体相容性,采用原位聚合法对CMSs和MWNTs分别进行表面修饰,制成核壳型结构的PET@CMSs(PCMSs)和PET@MWNTs(PMWNTs),并通过熔融共混法制备了PCMSs/PMWNTs/PET复合材料,对其阻燃性能进行探讨.使用TEM、SEM、FTIR、TGA、CONE等测试手段,表征了PCMSs与PMWNTs的结构及与PET基体的相容性,并测试了PCMSs/PMWNTs/PET的力学性能、阻燃性能、热稳定性和燃烧行为等.结果表明,与修饰前的CMSs/MWNTs相比,PCMSs/PMWNTs与PET基体具有更好的分散相容性,在PCMSs\PMWNTs添加的质量分数为1％,PCMSs与PMWNTs的质量比为1∶2时,PCMSs/PMWNTs/PET比CMSs/MWNTs/PET的抗拉强度提高的最大,可达26.1％;与纯PET、CMSs/MWNTs/PET相比,PCMSs/PMWNTs作为阻燃材料添加到PET中,具有较好的热稳定性、且有效延长了PET的点燃时间、增大FPI指数,从而降低火灾危险性,阻燃效果较好,其LOI值为28.1％,熔滴数为3 d/min,UL-94阻燃级别可达到V-0级.
