摘　　要：研究了碳纳米管管径、种类、含量以及偶联-三辊研磨-超声处理等工艺条件对碳纳米管/环氧树脂复合材料拉伸强度和电性能的影响。研究结果表明:三辊研磨-超声联用是均匀分散碳纳米管简单而有效的方法。较低的碳纳米管添加量(0.8%～4%)能大幅度提高环氧树脂的剪切强度和导电性能,添加量为3%时,复合材料的综合性能最优,即剪切强度提高了55.19%,表面/体积电阻率下降了8～10个数量级。CNTs/ER composites with good mechanical and conductive properties was prepared via coupling-three roller- sonication processing. The diameter, CNTs fraction and morphology of nanocomposites were investigated. The TEM results showed that coupling-three roller-sonication was a very simple and effective method for the dispersion of CNTs in matri~ Mechnical and electronical properties investigations suggested the optimal CNTs fraction of 3% will produce CNTs/ER composites with an in- crease in shear strength of 55.19% and a decrease in resistivity of 8-10 orders of magnitude
