Abstract:
A process for coating by electrochemically grafting a carbon based substrate with a polymer or copolymer, wherein use is made of an electrically conductive mixture comprising:a. at least one monomer able to form a polymer on said substrate;b. an aprotic solvent; andc. an electrolyte for increasing said electrical conductivity of said mixture, said mixture being subjected to electrolysis so as to create a cathode reaction wherein said carbon based substrate is used as a cathode to which a voltage is applied having a voltage value situated within an electrical potential range corresponding to a first inhibition peak so as to obtain in a first reaction step a first monomers' grafting on said carbon based substrate and in a second reaction step a polymerization of further monomers with the first monomers grafted on said cathode.
