摘要： A method for forming a coating on an electrically conductive surface is disclosed. The method comprises the steps of immersing the surface in a bath comprising an electrodepositable mixture of an intrinsically insulative polymer and an organic acid salt of an intrinsically conductive polymer, applying a voltage between an electrode and the surface in the bath to deposit a polymeric coating of the mixture on the surface, and curing the polymeric coating. The polymeric coating can be made electrically conductive by the additional step of immersing the polymeric coating in an organic acid after the deposition and before curing. A multilayered coating can be provided after curing the electrically conductive polymeric coating, by depositing a second or subsequent coating of an electrodepositable organic resin from an aqueous bath containing the resin on application of a voltage between an electrode and the electrically conductive polymeric subcoating in the bath. Also disclosed are resin compositions suitable for cationic electrodeposition.

摘要： Emulsion-polymerization of electrically conductive polyaniline salts is disclosed. The process comprises combining water, a water-solubilizing organic solvent, an organic acid that is soluble in the organic solvent, an aniline monomer, and a radical initiator. An organic phase forms which contains the polyaniline salt of the organic acid wherein the organic phase is separable from an aqueous phase. The polyaniline salt so formed is soluble in organic carrier solvents at a concentration of 25 w/w % or greater.
