Preparation and characterization of acrylonitrile-ethyl methacrylate copolymers and the effect of LiClO sub(4) salt on electrical properties of copolymer films

Copolymers of poly(acrylonitrile-co-ethyl methacrylate), P(AN-EMA), with three different EMA content and parent homopolymers were synthesized by emulsion polymerization. The chemical composition of copolymers were identified by FTIR, super(1)H-NMR and super(13)C-NMR spectroscopy. The thermal propert...

Description
Summary:Copolymers of poly(acrylonitrile-co-ethyl methacrylate), P(AN-EMA), with three different EMA content and parent homopolymers were synthesized by emulsion polymerization. The chemical composition of copolymers were identified by FTIR, super(1)H-NMR and super(13)C-NMR spectroscopy. The thermal properties of copolymers were modified by changing the EMA content in copolymer compositions. Various amounts of LiClO sub(4) salt loaded (PAN-co-PEMA) copolymer films were prepared by solution casting. The dielectric properties of these films at different temperatures and frequencies were investigated. It was found that the dielectric constant and ac-conductivity of copolymer films were strongly influenced by the salt amounts and EMA content in copolymers. copyright 2011 Wiley Periodicals, Inc.
