摘      要：Hexanoyl chitosan and polystyrene blends are immiscible by the elucidation of the glass transition temperature （Tg） as well as the viscometric and morphological analyses. Selective localization of the lithium salt in hexanoyl chitosan phase as the percolation pathway enhanced the conductivity in the blends as compared to the neat hexanoyl chitosan. The ionic conductivity of a polymer electrolyte is described by σ = enp. Thus, estimation of charge carrier density （n） and mobility （μ） is important in order to assess the performance. In this work, these parameters are calculated using impedance spectroscopy and FTIR.
