제목 Effect of Salt Concentration on Tg and Ionic Conductivity in PEG-co-PPG-PU/NaSCN Complexes
초록 A new type of solid polymer electrolyte (SPE) was synthesized by copolymerization of poly(ethylene glycol) and poly(propylene glycol). Salt (NaSCN) was added in the product. Solid polymer electrolytes (SPEs) were prepared with copolymers based on poly(ether urethanes) containing PEG and PPG blocks of different lengths and with different concentrations of sodium thiocynate. Its structure was confirmed as the fourier transform infrared spectroscopy (FT-IR). Effects of the salt concentration on the ionic conductivity (s) and the correlation between thermal and dynamic glass transition temperature of the complexed electrolytes thus prepared were investigated by using the alternating current (AC) impedance spectroscopy, differential scanning calorimetry (DSC) and dynamic mechanical thermal analyzer (DMTA).
