摘要
通过溶液混合法可以简单地制得多壁碳纳米管／聚氯乙烯复合材料。体积电阻率、拉伸强度等测试结果表明，随着碳纳米管含量的增加，碳纳米管在聚合物基体中的分散性降低，所得聚氯乙烯复合材料的体积电阻率呈非线性降低趋势，拉伸强度则呈先增加后降低的变化规律。碳纳米管含量为1％～2．5％（质量分数，下同）时所得复合材料的导电性和拉伸强度均较纯聚氯乙烯有较大改善。
Poly （vinyl chloride） based multi-walled carbon nanotubes composites could be simply produced by film casting. The influence of carbon nanotubes on the electrical resistivity and tensile strength of PVC was investigated. Results show that with the increase of the filled carbon nanotubes, the dispersion of carbon nanotubes in composites decreases, the volume resistivity of poly （vinyl chloride） composites decreases nonlinearly while the tensile strength of the composites first increases and then decreases. With carbon nanotubes＇ loading varying between 1.0 % and 2.5 %, the obtained composites demonstrate improved electrical conductivity and tensile strength for the PVC matrix.
