PURPOSE:To provide a high polymer material having electric conductivity imparted thereto at a low cost, by treating a high polymer material in an aque ous solution containing a copper salt, sulfur-releasing compound and nitrogen- containing organic compound having a specific number of carbon atoms. CONSTITUTION:A high polymer material other than fluororesin is dipped in an aqueous solution containing (A) a copper salt, e.g. cupric sulfate, cupric chloride or cupric nitrate, (B) a sulfur-releasing compound, e.g. sodium thiosul fate, acid sodium sulfite or sodium sulfide in an equimolar amount of a some what larger amount than the equimolar amount and (C) a water-soluble basic salt of a >=12C nitrogen-containing organic compound, e.g. laurylamine hydrochlo ride, dodecyldimethylamine hydrochloride, etc., in an amount of several % based on the total amount of the components (A) and (B), heated at a proper temperatur and wet heat-treated to react the components (A) with (B) and form copper sulfide in the monomolecular form. The resultant copper sulfide is capable of closely adhering to the surface layer part and interior of the high polymer material by the carrier action of the component (C) and impart the electric conductivity thereto. |
