Abstract
An electrically conducting material including a cyanic group-containing substrate material and adsorbed sulfides of copper and an auxiliary metal selected from silver, gold and elements of the platinum group. The cyanic group-containing substrate may be in the form of powder or a shaped body such as a fiber, film, plate, rod or like. Suitable substrates include synthetic polymers such as polyacrylonitrile and polyamides having cyanic groups; naturally occurring polymeric substances such as cotton having introduced thereinto cyanic groups; and low molecular weight compounds such as phthalonitrile. The electrically conducting material may be prepared by treating the cyanic group-containing substrate with (a) a source of monovalent copper ions, (b) a source of ions containing the auxiliary metal and (c) a sulfur-containing compound to form sulfides of copper and the auxiliary metal adsorbed by the cyanic group-containing material.
