Abstract

A process is disclosed for coating fine particles, in which the feed mixture contains: at least one monomer and/or at least one oligomer selected from monomers and/or oligomers of aromatic compounds and/or unsaturated hydrocarbon compounds suitable for forming an electroconductive oligomer, polymer, copolymer, block copolymer or graft copolymer; at least one type of anions which (1) are and/or can be incorporated as doping ions into the structure of the conductive polymer; (2) can be discharged from said structure in the event of a potential fall of the conductive polymer (reduction); and (3) can have an anti-corrosive effect in the presence of a metallic surface; at least one type of particles; if necessary, at least one oxidising agent and water and/or at least another solvent. A coating is formed from the feed mixture on the particle surface, the feed mixture being converted by oxidation into a conductive polymer in the presence of at least one type of mobile anti-corrosive anions. Alternatively, the fine particles are coated with a product mixture that contains a conductive polymer.
