Abstract

Ionic conductive gels have been synthesized by means ofMenschutkin reaction of poly(epichlorohydrin) (PECH) and 1,n-alkanediylbis- imidazolium (BIn, n=4, 6, 8) in acetonitrile or 1,4-dioxane. The obtained gels showed soft and flexible features. The gels showed ionic conductivity derived from Cl^- anions in PECH. The ionic conductivity of the gel in acetonitrile showed higher conductivity than that in 1,4-dioxane. The ionic conductivity increased with increasing of the molecular length of BIn. Temperature dependence of the gels was investigated to determine Vogel-Tammann-Fulcher (VTF) equation parameters. The results indicated that increasing of the crosslinking density accompanied by decrease of the molecular length of BIn should prevent the Cl^- anions from diffusing in the gels due to the increase of activation energy of the ion transport.
