Effect of Nanofiller on FTIR, DSC and DC Conductivity Studies of PVP Based Polymer Films

Abstract

Nanocomposite polymer films (NCPs) are prepared by doping of potassium acetate (CH₃COOK) in polymer of polyvinyl pyrrolidone (PVP) by dispersing aluminium oxide (Al₂O₃) by different weight percentile ratios using solution cast technique. The obtained NCPs’ films were characterized and reported. Complex analysis between NCs and host polymer was confirmed by FTIR. DSC analysis states the glass transition temperature, T_g=77^oC at which the phase transformation changes from glassy to rubbery amorphous phase. The maximum ionic conductivity was found to be 2.02×10^-3 S/cm for the prepared film PVP:CH₃COOK:Al₂O₃ (80:20:1%). With the proposed wt% ratios of polymer films, solid polymer battery has been fabricated and the discharge characteristics of the cell were studied.
