Abstract

A kind of nanocomposite polymer based on poly(acrylonitrile-methyl methacrylate) [P(AN-MMA)] copolymer was prepared by in situ polymerization of monomers on the surface of TiO2 nanoparticles, which come from the hydrolysis of Ti(OC4H9)4. Analysis of Fourier transform-infrared (FT-IR) spectra indicated that the acrylonitrile (AN) monomers copolymerized with the methyl methacrylate (MMA) monomers by breaking their own double bonds. The dependence of ionic conductivity on temperature for the resulting nanocomposite polymer electrolyte (NCPE) followed the Arrhenius equation. The ionic conductivity of the NCPE was 1.12 × 10–3 S cm–1 at room temperature when the nanocomposite polymer membrane (NPM) contained 10.8 % of mass fraction of TiO2 nanoparticles.
