Grafting and growing mechanisms of polymerised organic films onto metallic surfaces

Abstract The build up of a homogeneous polyacrylonitrile film laid down by electropolymerisation on a metallic surface begins by the chemisorption of a monomer monolayer. As the growth of the conducing film proceeds (conduction by hopping) the number of electrons is constant. The electronic properties of the substrate and monolayer (conjugated molecule) are important.
