Abstract
Abstract A process for producing an electrically conductive composite polymer article, which comprises contacting at least one polymerizable compound selected from the group consisting of heterocyclic compounds, derivatives thereof, aniline and aniline derivatives with a polymer article containing a polymerization catalyst for the polymerizable compound, and polymerizing the polymerizable compound to prepare an electrically conductive polymer on the surface of the polymer article or on the surface and in the polymer article. Schottky-barrier diodes and patterned electrodes can also be produced by utilizing the process. According to the process, process steps can be simplified, and various devices having excellent conductivity and transparency can be produced.
