Abstract
A process for preparing articles having a fluorocarbonsulfonic ionomer layer, such as membranes and catalysts, is disclosed wherein the fluorocarbonsulfonic ionomer is deposited upon support using an new annealing process. The annealing process of the present invention includes the step of heating a fluorocarbonsulfonic ionomer coated substrate in the presence of a vaporous solvent. This process provides for fluorocarbonsulfonic ionomer coated articles which can be annealed quickly at temperatures below the degradation point of many desirable support materials.
