摘要:
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.

摘要:
An electrochemical cell (10) includes first and second electrodes (12) and (14) with an electrolyte system (26) disposed therebetween. The electrolyte system is fabricated of a blend of differing grades of a single polymer. One grade may be provided to, for example, absorb an electrolyte active species, while the second grade may be provided to enhance mechanical integrity of the system.
