Fabrication and characterization of free-standing polyaniline-polyvinyl acetate films 2015 Illustrations PAni doped with HCIO4 was synthesized and mixed to PVA in different wt% ratio: 5:95, 25:75, 50:50 and 75:25. The polymer blends were then pressed between hot rollers of calendaring machine to yield PAni-PVA films. FTIR spectroscopy of the films shows the presence of characteristic peaks of both PAni-PVA. The PAni-PVA film of 50:50 wt% ratio gives the highest elastic modulus which may be due to the strong PAni-PVA particles interaction. Lastly, the electrical conductivity increases exponentially with increasing concentration of PAni. This suggests possible tunneling-assisted conduction.
