A method for the production of a processable electrically conductive polymer which comprises the steps of:
- electropolymerizing an electropolymerizable monomer onto an anode in an electrolytic medium, said electrolytic medium comprising a reaction solvent for an electropolymerizable monomer, an electropolymerizable monomer exhibiting solubility in said reaction solvent, and a polymeric electrolyte having anionic surface character for affiliation with the cationic electropolymerized polymer on said anode, said polymeric electrolyte being present in said electrolytic medium in a dispersed phase during the electropolymerization of the electropolymerizable monomer, said anode being an electrically conductive anode processed from a processable conductive polymer material comprising an oxidatively polymerized polymer having cationic character in affiliation with a polymeric counteranion particle having anionic surface character;
- and
- processing together, the electropolymerized polymer and the anode on which it is formed, by shaping the electropolymerized polymer and anode or by size reducing the electropolymerized polymer and anode and dispersing the resulting size reduced material into a liquid vehicle therefor for production of a coatable composition.
A method for the production of a processable polypyrrole which comprises the steps of:
- electropolymerizing pyrrole onto an anode in an aqueous electrolytic medium, said electrolytic medium having dispersed therein during the electropolymerization polymeric latex particles having anionic surface character, said anode being an electrically conductive anode processed from a processable conductive polymer material comprising an oxidatively polymerized polymer having cationic character in affiliation with a polymeric counteranion particle having anionic surface character;
- and
- processing together, the polypyrrole and the anode on which it is formed, by shaping the polypyrrole and the anode or by size reducing the polypyrrole and anode and dispersing the resulting size reduced material into a liquid vehicle therefor for production of a coatable polypyrrole composition.
