摘要
测定了在不同pH值的盐酸溶液中掺杂聚苯胺的电导率及其温度依赖性和电压依赖性,在pH=3～4之间,聚苯胺电导有一个很大变化,结果表明聚苯胺的电导更符合VRH模型,估算得聚苯胺的共轭链重复单元数约为34。首次报道了聚苯胺(pH=6.3)介电系数的温度谱和频率谱。
The conductivity and its temperature and frequency dependence of polyaniline doped with various pH values have been measured. There is big change of conductivity in the range of pH=3-4. The experimental results showed that the conductivity of polyaniline was agreement with VRH model. The repeat length of conjugated chain was estimated and was 34. The temperature and frequency spectra of dielectric constant of polyaniline with pH=6.3 were reported for the first time.
