On the electrochemical polymerization of acrylonitrile and N-vinylpyrrolidone : new insight into the mechanism

The protection of metals against environmental attack can be achieved by coating the metal with a protective organic film. Poor adhesion of the organic film to the metal surface has, however, limited the success of this approach. Here it is demonstrated that polyacrylonitride can be elecrografted onto a nickel surface producing a strongly adherent film. The transformation of the organic film could also open the way to new polymer-metal composites.
