Electrically conductive polymer material having conductivity gradient

摘要

A conductive polymeric material such as a textile fabric having a conductive polymer film may be treated with a solution containing a chemical reducing agent to reduce its conductivity. By selectively reducing portions of the conductive polymer in varying degrees, a gradient of conductivity may be produced in the material. After the conductive polymer has been reduced to a target level, the reducing solution may be removed with a hot water rinse.
