Abstract
This paper reports experiments on forming a layer composed of graft polymers with pendant oligo(oxyethylene) chains directly onto the surface of a polyaniline film by plasma-graft polymerization. The graft polymers were covalently bonded with polyaniline film. Vinyl monomer with pendant oligo(oxyethylene) chain was synthesized and used for plasma-graft polymerization. The polyaniline film was irradiated with argon plasma to form active radicals on its surface, and then immersed in monomer solution to graft polymerize at 293 K. A graft layer composed of linear polymers with pendant oligo(oxyethylene) chains was formed on the surface of the film and the average thickness of the graft layer increased with polymerization time and concentration of monomer solution. A graft layer of crosslinked polymers was also formed using the vinyl monomer and divinyl monomer having an oligo(oxyethylene) chain. The graft layer comosed of crosslinked polymers became ion-conductive by inclusion of LiClO4. The interface resistance between the polyaniline film and graft layer decreased, compared with that between the film and freestanding polymer solid electrolyte photopolymerized with the same compositions of monomers as the graft layer.
