영문 초록

Novel lithium polyelectrolyte based on ionic liquids have been prepared and characterized of their properties. Ionic conductivity, glass transition temperature and viscosity and thermal properties of gel polyelectrolytes which were composed of poly (lithium 2-acrylamido-2-methyl propanesulfonate) based on-ethyl-3-methylimidazolium tricyanomethanide (emlmTCM) and N,N-dimethyl-N-propyl—N-butyl ammonium tricyanomethanide (N1134 TCM) and N,N-dimethyl-N -propyl—N-butyl ammonium dicyanamide (N1134DCA) were measured. The ionic conductivity of this polyelectrolyte with ionic liquid (emlmTCM) exhibits higher conductivity (1.28*10-3 S/cm) than that of polyelectrolyte with N1134 TCM (6.3*10-4S/cm) and Nn34DCA(6.0*10-4 S/cm). Because of using the polymerizable group is seemed to maintain high flexibility of imidazolium cation effectively to exhibit the higher conductivity. The viscosity of emlmTCM (.19.56cP) is lower than that of N1134 TCM (28.61cP) and N 1134 DCA (28.72cP). Lower viscosity and dissociation of lithium cations from the polymer chains exhibit the higher conductivity.
