摘　　要：采用熔融共混法制备了聚苯硫醚(PPS)/乙烯-丙烯酸甲酯-甲基丙烯酸缩水甘油酯(E-MA-GMA)/玻璃纤维(GF)/埃洛石纳米管(HNTs)混杂复合材料,研究了其力学性能、热性能、阻燃性能及其微观形态。结果表明,当E-MA-GMA在PPS/E-MA-GMA共混体系中的质量分数为12%、GF的质量分数为30%、HNTs质量分数为6%时,复合材料具有较好的综合性能。此时复合材料的拉伸强度、弯曲强度及缺口冲击强度较纯PPS分别提高了145.3%、83.2%、338.3%,复合材料的热变形温度达到237.1℃;极限氧指数高达52.5%。扫描电子显微镜显示E-MA-GMA较均匀地分散在PPS基体中,GF、HNTs在基体树脂体系中表现出不同的尺寸;偶联剂的应用极大地改善了GF、HNTs与PPS基体树脂之间的界面结合。Polyphenylene sulfide （PPS）/Ethylene-methacrylate-glycidyl methacrylate （E-MA-GMA）/Glass fiber （GF）/Halloysite nanotubes（HNTs） hybrid composites were prepared by means of melt blending. The mechanical properties, thermal property, flame-retardant property and the morphologies of the composites were investigated. The results showed that when the mass fraction of E-MA-GMA in PPS/E-MA-GMA blends was 12%, the mass fraction of GF and HNTs was 30% and 6%, the composites had better comprehensive properties. The tensile strength, flexural strength and notched impact strength of composites were increased by 145.3%, 83.2%, 338.3% respectively compared with pure PPS. The limit oxygen index was up to 52.5% and heat distortion temperature achieved about 237.1 ℃. SEM revealed that GF and HNTs had good dispersibility in the matrix of PPS, and the diameter of GF was dif- ferent with that of HNTs. The application of coupling agent KH550 improved interface bonding of GF, HNTs and PPS.
