Abstract
Poly(vinylsulfonic acid) chains having cation-exchangeable groups are introduced onto a surface of polyaniline film by means of plasma-graft polymerization, and the redox reaction mechanism of the plasma-grafted polyaniline film is investigated with a combination of electrochemical and microgravimetric techniques. It becomes apparent from the surface analyses of the polyaniline film that poly(vinylsulfonic acid) chains are plasma-grafted. The graft area is not covered on all the surface of the film and is formed locally here and there on the surface. The plasma-grafted film exhibits both anion and cation migrations which take place in order to maintain electroneutrality of the film during the redox process in an electrolyte. The cation migration takes place predominantly through thickening of the graft layer composed of poly(vinylsulfonic acid) chains and extending of the graft area.
