The electrical conductivity both dc and ac of polypyrrole doped with β-naphthalenesulfonicacid (NSA) and polypyrrole-polymethyl methacrylate blends have been investigated in the temperature range of 300-80K and in the frequency range of 100-10MHz. Samples are prepared by in situ polymerisation technique using the common solvent meta cresol. The frequency dependence of conductivity satisfies the power...
The dc and ac conductivity of polyaniline (PANI)-polyvinyl alcohol (PVA) blends have been reported from room temperature to 80K in the frequency range of 1kHz-5MHz. The dc conductivity has been described by the variable range hopping (VRH) model. The large value of VRH exponent (>0.5) indicates that hopping transport occurs between the superlocalised states of polymer. The frequency (ω) dependence...
