Hexanoyl Chitosan-Polystyrene Blend Based Composite Polymer Electrolyte with Surface Treated TiO₂ Fillers

Abstract:

Composite polymer electrolytes (CPEs) comprised of hexanoyl chitosan-polystyrene-LiCF₃SO₃-TiO₂ were prepared by solution casting technique. The TiO₂ fillers were treated with 4% sulphuric acid (H₂SO₄) aqueous solution. The effect of treated TiO₂ on the structural and electrical behaviour of the prepared electrolyte systems was investigated by X-ray diffraction (XRD) and impedance spectroscopy, respectively. Addition of TiO₂ decreases the crystallinity of the electrolytes. Ac conductivity was calculated from σ(ω) = ε_oε_rωtanδ. It is found that at all frequencies, σ(ω) increases with increasing temperature. Dielectric constant decreases with increasing frequency and increases with increasing temperature.
