摘要
采用溶液混合法制备了环氧树脂/碳纳米管复合材料,探讨了碳纳米管的含量对复合材料拉伸和导电性能的影响。结果表明:随着碳纳米管含量的增加,复合材料的拉伸强度、杨氏模量和断裂伸长率均先提高后降低;当其质量分数为0.6%时,复合材料拉伸性能达到最优值且比纯环氧树脂分别提高了82.5%,40.2%和43.8%。复合材料的电导率呈现典型的渗阈行为,当碳纳米管的质量分数为1.8%时,复合材料电导率为1.31×10-5S/m,达到了半导体级别。
Abstract. Epoxy rens lution blending method. in/carbon Tensile nanotubes （CNTs） co and electrical propertl were discussed. Test results of tensile properties sh mposltes w es of the owed that ere fabricated via a soas-prepared composites the tensile strength, Young＇s modulus and elongation at break were first increased and then decreased with the increasing of the CNTs loading. When it was 0.6%, they reached the maximum values which were 82.5%, 40.2% and 43.8%,respectively, and more than those of the pure epoxy samples. Moreover, test results of conductive properties showed that there was typical percolation behaviour for the as-prepared samples. The conductivity of the as-prepared sample was 1.31×10^-5S/m when the CNTs loading was 1.8%, which achieved the semiconducfor grade.
