摘　　要：采用一步原位聚合合成了MC尼龙6/ZnO纳米复合材料。对合成工艺条件和MC尼龙6/ZnO纳米复合材料的性能进行了研究。研究表明,当超声温度为80℃,超声时间为20min,偶联剂加入量为1%时,合成的MC尼龙6/ZnO纳米复合材料力学性能最优。纳米ZnO在基体中达到了纳米级的分散,起到同时增强增韧的作用;MC尼龙6/纳米ZnO复合材料表面电阻系数比MC尼龙6降了105倍;摩擦系数降低了0.15;起始降解温度提高了9℃,最大失重速率温度提高了21℃。说明一步合成MC尼龙6/纳米ZnO复合材料的抗静电性能、摩擦磨损性能和热稳定性都明显优于MC尼龙6。The nanocomposites of MC nylon 6/ZnO were prepared by the direct in-situ polymerization. The processing parameters and the properties of MC nylon 6/ZnO nanocomposites were studied. The results show that the properties of MC nylon 6/ZnO nanocomposites will be best with the following optimized parameters： supersonic dispersing at 80℃ for 20 min, and adding 1% of the coupling agent. ZnO is dispersed in the matrix as the nanosized particles. And the strength and toughness of the nanocomposites is improved. The surface resistance coefficient of MC nylon 6/ZnO nanocomposites is decreased 105 times than that of MC nylon 6, the friction coefficient is decreased 0.15, the onset of degradation temperature is increased 9 ℃, and the maximum temperature of mass loss rate is increases 21℃. The test indicates that the antistatic, friction properties and thermal stability of MC nylon 6/ ZnO nanocomposites by the direct in-situ polymerization are better than these of MC nylon 6.
