Official abstract text for this publication.
A conductive polymer-metal complex becomes to be adhered simply and strongly on the surface of a substrate such as PTFE. By subjecting a solution containing a monomer which provides a conductive polymer, an anion, and a metal ions such as Ag + , Cu 2+ , Cu + and the like to an irradiation with light having an energy required for exciting an electron to an energy level capable of reducing the metal ion, such as ultraviolet light, under an appropriated condition, thereby precipitating the conductive polymer-metal complex as being dispersed in the reaction liquid. By supplying this dispersion liquid onto various substrates, the complex microparticles in the dispersion liquid enter into and mate with the narrow holes on the surface of the substrate. As a result, the complex precipitate formed on the surface of the substrate and the substrate can be adhered strongly to each other.
