ABSTRACT:
A method for forming a hydrophilic coating upon a porous substrate such as a reticulate electrode or a filter from a dispersed, perfluorocarbon copolymer. Perfluorocarbon copolymer is dispersed in a solvating medium, a substantial portion, but not necessarily all of the perfluorocarbon being solvated. The dispersion is applied to the substrate and the dispersion medium is removed.
