Amine oxide coating compositions
Abstract
An aqueous coating composition is provided comprising carbon particles, one or more highly fluorinated polymers and one or more amine oxide surfactants, typically an amine oxide surfactant according to formula I: where n is 9 to 19. The coating composition is advantageously used in a method of making a gas diffusion layer for an electrochemical cell comprising the steps of: a) coating a electrically conductive porous substrate with the aqueous coating composition, and b) heating the electrically conductive porous substrate to a temperature sufficient to decompose the amine oxide surfactants. In another aspect, a gas diffusion layer for an electrochemical cell is provided which is advantageously free of surfactant.
