Electrically conducting material and process of preparing same.

摘要

An electrically conducting material including a cyanic group-containing material having adsorbed thereby sulphides of copper and an auxiliary metal selected from silver, gold and elements of the platinum group. The cyanic group-containing material is in the form of powder or a shaped body such as fibre, film, plate, rod or like and is formed of a synthetic polymer such as polyacrylonitrile or a polyamide having introduced thereinto cyanic groups; a naturally occurring polymeric substance such as cotton having introduced thereinto cyanic groups; or a low molecular compound such as phthalonitrile. The electrically conducting material may be prepared by treating the cyanic group-containing material with (a) a source of monovalent copper ions, (b) a source of ions containing the auxiliary metal and (c) a sulphur-containing compound to form sulphides of copper and the auxiliary metal adsorbed by the cyanic group-containing material.
