PURPOSE:To form a high-molecular material which is firm and has high stable electrical conductivity, by forming an electrically conductive layer composed of copper sulfide on the surface or both on the surface and in the interior of a high-molecular material contg. a mercaptobenzimidazole or thiourea compd. CONSTITUTION:An electrically conductive layer composed of copper sulfide is formed on the surface or both on the surface and in the interior of a high- molecular material contg. at least one compd. selected from among mercaptobenzimidazole, mercaptobenzothiazole and thiourea compds. Said mercaptobenzimidazole compd., etc., can be incorporated in the high-molecular compd. by blending, adsorption or immersion. The copper sulfide layer on the surface or both on the surface and in the interior of the high-molecular material can be formed by allowing a caprous ion to be adsorbed by a knitted fabric made of a polymer and treating it with a compd. capable of releasing either or both of sulfur atom and sulfur ion (e.g. sodium sulfide or sodium thiosulfate). |
