  • Publication number: 20120208086
    Abstract: A process for coating fine particles, in which the feed mixture contains: a monomer and/or an oligomer of aromatic compounds 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 a of mobile anti-corrosive anion.

  • Publication number: 20120052307
    Abstract: A process for coating metallic surfaces with an anti-corrosive composition that contains a conductive polymer and is a dispersion that contains the at least one conductive polymer mainly or entirely in particulate form, as well as a binder system. The conductive polymer is at least one polymer based on polyphenylene, polyfuran, polyimidazole, polyphenanthrene, polypyrrole, polythiophene and polythiophenylene charged with anti-corrosive mobile anions. Alternatively, the metallic surfaces can be first coated with a dispersion based on conductive polymers in particulate form, then coated with a composition which contains a binder system.

  • Publication number: 20080175992
    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 anticorrosive 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.

  • Publication number: 20080171211
    Abstract: The invention relates to a method for protecting a metal surface by means of a coating based on a corrosion-inhibiting composition containing the following component(s): a) at least one type of deposit substance comprising (1) anions incorporated by an oxidation reaction and (2) releasing at least a part of said anions for a potential variation between a redox potential of the deposit substance and an undisturbed corrosion potential of a metal surface or when a comparably small potential variation is produced on a defect, wherein said anions can inhibit a partial anodic or/and cathodic corrosion reaction or/and act as an adherence initiator, said anions comprise, respectively, an ionic radius non-impairing the migration thereof, possibly b) at least one type of matrix substance, wherein said deposit substance(s) disposed in the undisturbed areas of the coating are at least partially oxidised or at least partially doped by the anions and at least one type of the deposit substance in the disturbed areas of the
