Electrical Studies On Hexanoyl Chitosan-based Nanocomposite Polymer Electrolytes

摘要

Hexanoyl chitosan-based nanocomposite polymer electrolytes were prepared using solution casting technique. The effect of addition of nanosize titanium oxide, TiO_2 as the filler on the electrical properties of the prepared electrolyte system was investigated by impedance spectroscopy. The maximum conductivity of 3.06 x 10~(-4) S cm~(-1) was achieved with addition of 6 wt%. TiO_2 which is 1 order of magnitude higher than the filler-free electrolyte sample (σ = 1.83 x 10~(-5) S cm~(-1)). The Rice and Roth model was proposed to explain the conductivity variation for the prepared electrolyte system. The ac conductivity of hexanoyl chitosan-based nanocomposite electrolytes was also analyzed.
