New family of anion conducting polymers: synthesis and characterization

Abstract

Single-anion conducting polyether networks have been synthesized and investigated. They have been prepared by cross-linking a quaternary ammonium salt with an unsaturated prepolymer. Anion conducting networks have been prepared with various anions such as F −, Cl −, Br −, I −, BF 4 − and (CF 3SO 2) 2N − by cross-linking appropriate diallyldimethylammonium salts with an unsaturated polyether. The conductivity measurements revealed that anionic conductivity increases, in the halide serie, with the anion size and more generally with the nucleophilicity decrease. This is mainly related to an increase in charge carriers due to an easier dissociation. The Arrhenius plots are not linear suggesting, as in salt–polymer complexes, a VTF behavior.
