Abstract
Non-evaporative processes for coating ion-containing polymers onto selected substrates and the articles made thereby, which processes fundamentally comprise contacting a substrate with a dispersion or solution of an ion-containing polymer and especially a solventless dispersion of a perfluorosulfonic acid ionomer, and thereafter contacting the dispersion- or solution-wetted substrate with a solution of a salt or of a strongly ionizing acid of a sufficient concentration to cause an adherent coating of the ion-containing polymer to be formed on the substrate.
