摘要
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。
Polyphenylene sulfide （PPS）/Polyamide 6,6 （PA66）/halloysite nanotubes （HNTs） composites were prepared by means of melt blending. The mechanical properties, the morphologies and the thermal properties of the composites were investigated. The results showed that in the case of PPS/PA66（60/40） and 30% HNTs, the values of tensile strength, flexural modulus and notched impact strength of the composites were increased by 36.6%, 163.5%, 104% respectively. The differential scanning calorimeter （DSC） showed that PPS can compensate and interact with PA66 in some degree . Scanning electron microscope （SEM） revealed that HNTs had good dispersibility in the polymer matrix, and the compatilizer can improve the interfacial strength between PPS and PA66 and the effect of the HNTs＇ dispersibility in the composites.
