제목 Electrochemical characterization of Photo-curable biopolymer electrolyte containing Acrylated Chitosan and Methacrylated alginate
초록 Photo-curable biopolymer electrolyte comprising the blend of Acrylated Chitosan (AC) and Methacrylated Alginate (MA) as host polymer and LiClO4 in ethylene carbonate as liquid electrolyte is prepared by Ultra Violet (UV) curing technique. The conductivity has been investigated as a function of AC and MA polymer blend ratio with fixed content of liquid electrolyte at temperature range of 298.15K-358.15K using impedance spectroscopy. The maximum conductivity is found to be 3.222E-03 S/cm at 298.15K for 5 to 5 ratio (AC/MA) concentration. The coordination of liquid electrolyte to the 5 to 5 ratio (AC/MA) concentration was shown to play an important role for physical state such as free volume. To verify this reason, emphasis is placed on the application of Arrhenius equation, the effects of activation energy, glass temperature and carrier density are taken into account.
