An Investigation on Electric Properties of the Polyaniline Complexes under High Pressure
-
摘要: 本文研究了大共轭键结构的聚苯胺等高聚物在高压下的电学性能,其结果表明PAn-H+的电阻值在p=3.2 GPa下出现极小值,可作3.2 GPa压力下的定标物质。并指出聚苯胺系列导体属于电子性导电物质,而且在不同的压力条件下电流和电压的关系均表现为非线性。Abstract: Electric properties of the polyaniline with large conjugated -bonds have been studied under high pressure. It shows that a minimum of electric resistance-pressure curve for the PAn-H+ occurs at p=3.2 GPa, which suggests that the PAn-H+ may be used as a pressure-calibration material of p=3.2 GPa. And voltage-current curves display nonlinear characterization at various pressure conditions.
