Reinforced perfluorocarboxylic acid ion exchange membrane with bubble thinning function and preparation method thereof

The invention belongs to the technical field of ion exchange membranes, and particularly relates to a reinforced perfluorocarboxylic acid ion exchange membrane with a bubble dredging function and a preparation method thereof. The reinforced perfluorocarboxylic acid ion exchange membrane with the bubble thinning function is composed of a perfluorocarboxylic acid polymer layer, a porous reinforcingmaterial layer and functional surface coatings, the functional surface coatings are located on the upper surface and the lower surface of the perfluorocarboxylic acid polymer layer, the porous reinforcing material layer is embedded in the perfluorocarboxylic acid polymer layer, and the functional surface coating is of a porous rough structure composed of a perfluorinated ionic polymer. The reinforced perfluorocarboxylic acid ion exchange membrane with the bubble thinning function can effectively reduce the cell voltage, reduce the electrolysis energy consumption and reduce the production costin a novel zero-polar-dist
