采用熔融共混方法制备了聚苯硫醚(PPS)/尼龙-66(PA66)/埃洛石纳米管(HNTs)复合材料,研究了其力学性能、热性能及其微观形态.结果表明:当PPS/PA66的比为60/40、HNTs的含量为30%时,复合材料具有较好的性能.复合材料的拉伸强度、弯曲模量及缺口抗冲击强度相对纯PPS分别提高了36.6%、163.5%、104%.差示扫描量热(DSC)的分析说明PPS与PA66两组分在熔体中有一定的相容性及相互作用.扫描电子显微镜(SEM)显示,PA66呈链珠状分散于PPS基体中,HNTs在PPS/PA66体系中具有很好的分散性,并形成微纤状结构.相容剂的加入有利于改善PPS/PA66之间的界面结合以及HNTs在复合体系中的分散效果.
