用纳米导电纤维填充天然胶乳制得复合材料 ,研究了复合材料的导电性、介电性以及温度对复合材料电阻率的影响。结果表明 ,随纳米导电纤维填充份数的增加 ,复合材料的电阻率下降 ,介电常数增大 ;电阻率对温度的依赖性较大 ,并且当纳米导电纤维尚未在胶乳中形成导电网络时 ,体积电阻率和表面电阻率随温度升高表现出不同的变化趋势。 Composite nanofibers were filled with nanofibers and the effects of electrical conductivity, dielectric property and temperature on the resistivity of the composites were investigated. The results show that the resistivity of the composites decreases and the dielectric constant increases with the increase of the filled fraction of nano-conductive fibers. The dependence of the resistivity on the temperature is larger, and when the nano-conductive fibers have not formed the conductive network in the latex, Volume resistivity and surface resistivity show different trends with increasing temperature.
