Abstract

Polypyrrole-polyvinyl alcohol (PPy-PVA) nanocomposite is synthesized by dispersing interface polymerized polypyrrole in PVA matrix. The composite films are characterized by FTIR, XRD and SEM. FTIR spectra indicates crosslinking in the composite film. XRD pictures show more crystallinity for higher polymerization temperature, whereas SEM pictures clearly indicate PPy rod formation for the same film. The electrical conductivity of the films is in the range of 10−1 S/cm, whereas the current-voltage (I–V) characteristics shows power law behaviour.
