A.C. CONDUCTIVITY STUDY IN POLYMER COMPOSITE FILMS (PVC-PVAc) DOPED WITH CONDUCTING POLYMER POLYANILINE (PANI)

摘要

Dielectric properties and a.c. electrical conductivity of polyvinyl chloride (PVC)-polyvinyl acetate (PVAc) composite film doped with polyaniline at low temperatures in frequency range from 50 Hz to 1 × 10~3 KHz have been studied. The Decrease in dielectric constant and increase in a.c. conductivity with increase in frequency in higher frequency range have been explained. The increase in a.c. conductivity due to doping of PANI has been explained on the basis of protonic doping of PAIN. The composite films have been characterized by employing X-ray diffraction.
