| 研究不同预分散熔融混炼工艺对丁基橡胶（IIR）/单壁碳纳米管（SWCNTs）导电复合材料性能的影响。结果表明：先将SWCNTs在溶剂或分散剂溶液中超声预分散处理，再将其与IIR等进行湿法熔融混炼，可以制得导电性能优良的IIR/SWCNTs导电复合材料，SWCNTs的分散性和复合材料的导电性能均优于采用传统熔融混炼工艺制备的复合材料；采用聚氧乙烯辛基苯酚醚-10水溶液超声预分散处理，SWCNTs在IIR基体中的分散性最好，复合材料的导电性能最优异；采用正己烷超声预分散处理，SWCNTs的分散性和复合材料的导电性能适中；采用乙醇超声预分散处理，SWCNTs的分散性较差，但复合材料的导电性能仍优于传统熔融混炼工艺复合材料。 |

| The effects of different pre-dispersion melt mixing processes on the properties of IIR/SWCNTs conductive composites were investigated.The results showed that the IIR/SWCNTs conductive composites with excellent electrical conductivity could be prepared by ultrasonic treatment of pre-dispersing SWCNTs in solvent or dispersant solution and then wet melt mixing with IIR，etc.The dispersibility of SWCNTs in IIR matrix and the conductivity of the composites were superior to those prepared by traditional melt mixing process.SWCNTs displayed the best dispersion in IIR matrix and the conductivity of the composites was the highest when OP-10 aqueous solution was used for ultrasonic pre-dispersion treatment.The dispersion of SWCNTs and the conductivity of the composites were moderate when n-hexane was used as ultrasonic pre-dispersion solvent.The dispersion of SWCNTs was poor when ethanol was used for ultrasonic pre-dispersion treatment，but the conductivity of the composite was still better than that of the composite prepared by traditional melt mixing process. |
