Abstract
A method for making a device in which a conductive polyaniline layer (polyaniline salt layer) is formed on a substrate and patterned into a desired configuration, is disclosed. The polyaniline salt containing layer is formed by applying a polyaniline salt solution which combines a mixture of polyaniline and an additive, dissolved in a solvent on the substrate. Thereafter, the polyaniline salt containing layer is patterned by delineating in such layer at least one region having a conductivity less than about 10.sup.-6 S/cm. The at least one region in the polyaniline salt containing layer having a conductivity less than about 10.sup.-6 S/cm is optionally formed by combining a photobase generator (PBG) with the polyaniline salt solution. An adhesive is optionally mixed with the polyaniline salt solution for forming an polyaniline salt/adhesive polymer layer which is patterned into the desired configuration.
