Preparation of PANI-PVA Composite Film with High Conductivity

Abstract

The PANI-PVA composite films adopting PVA as the base material and doped with hydrochloride, DBSA, amino sulfonic acid aqueous solution were prepared and their conductivity was compared. Among these PANI-PVA composite films, the conductivity of HCl-PANI-PVA film is the highest. At the same time, the influences of mass ratio between PANI and PVA, acid content, oxidant content, reaction time and drying temperature of film on the conductivity of HCl-PANI-PVA film were studied. The result shows that the conductivity of HCl-PANI-PVA film is the highest when the mass percentage of PVA is 40%; the C(HC1) = 0.5 mol/L; the n(APS/An) = 1.0; the reaction time is 6 hours and the drying temperature of the film is 80˚C, and that the maximum conductivity of HCl-PANI- PVA film is 16.0 S∙cm−1.
