Abstract
Articles are designed with a substrate and have either a uniform layer or pattern of electrically-conductive polyaniline on one or both supporting sides of the substrate. The electrically-conductive polyaniline is disposed either within, on top of, or both within and on top of, a uniform or pattern of a crosslinked polymer that is derived from a photocurable composition comprising water-soluble reactive polymer comprising (a) greater than 40 mol % of recurring units comprising sulfonic acid or sulfonate groups, (b) at least 5 mol % of recurring units comprising a pendant group capable of crosslinking via [2+2] photocycloaddition, and optionally (c) at least 1 mol % of recurring units comprising a pendant amide, hydroxyl, lactam, phosphonic acid, phosphonate, carboxylic acid, or carboxylate group, all amounts based on the total recurring units in the water-soluble reactive polymer.
