A method of manufacturing an intrinsically conductive polymer crosslinking at least a portion of an intrinsically conductive polymer precursor in the solid state, the swollen state, or combinations comprising at least one of the foregoing states, wherein the swollen state is characterized as being one wherein the intrinsically conductive polymer precursor increases in volume upon exposure to a solvent without completely dissolving in the solvent. In another embodiment, a method of manufacturing a pattern comprises casting a film of an intrinsically conductive polymer precursor on a substrate; and crosslinking at least a portion of the film by oxidation, wherein the crosslinking occurs in the solid state, the swollen state or combinations comprising at least one of the foregoing states.
