摘要：

Thin films of poly left bracket (oligo(oxyethylene) methacrylate)-co-(alkali-metal methacrylates) right bracket were prepared from methanol solutions of oligo(oxyethylene) methacrylate and alkali-metal methacrylates by casting and polymerization on a Teflon plate under nitrogen. The ionic conductivity of the films depends on the electrolyte content, the dissociation energy of the alkali-metal methacrylate, and the degree of motion of polymer segments surrounding the ions in the polymer matrix. The ionic conductivity of the polymeric Li and K salts is 10** minus **6 S/cm at 80 degree C. The transient ionic current after reversing the dc bias polarity shows one sharp peak corresponding to cation migration, indicating that the polymer is a cationic single-ion conductor.
