摘要: Polyaniline-polyvinyl alcohol (PANI-PVA) interpenetrating network composite film is successfully prepared by in situ polymerization of aniline within PVA embedded with different concentrations potassium dichromate (K2Cr2O7). The resulted characterized UV-Visible spectroscopy, SEM and XRD, TGA techniques confirmed the formation PANI matrix. Electrical conductivity films increase from 10−6 to 10−2 S/cm loading 10−4 10−2M. Further, exposing humidity environment, increases 14 100% conditions 11.3 84.3%.
