摘要
本文研究了纳米导电纤维（Nano-F）与导电炭黑（HG－CB）填充硅橡胶复合材料的电性能，Nano－F／HG—CB填充硅橡胶复合材料具有高的导电性；电阻率随温度增加在25～40℃之间呈负温度系数，而在40～120℃之间电阻率变化不大，具有较高的热稳定性；在不同温度下的伏-安特性呈欧姆线性关系．探讨了这种复合材料的导电机理．
Electric property of silicone rubber composite filled with nano-conductive fibre and conduCtive carbon-black was investigated. It was shown that the composite possessed high electric conduCtivity and resist-heat stability. With temperature increasing, the resistivity of the composite gradually decreased (NTC, negative temperature coefficient) at the range of 25 to 40 ℃, but there existed small change at the range of 40 to 120℃. The results showed that the U ～ I characteristic of the composite was consistent with Ohm law.
