Abstract
An electrically conducting material including a polymeric material having adsorbed sulfides of a first metal selected from copper, cobalt, tin, mercury and of lead and a second metal selected from silver, gold and elements of the platinum group. The polymeric material is in the form of powder or a shaped body such as a fiber, film or string and is formed of a synthetic polymer without cyanic groups such as a polyester or a polyamide or a naturally occurring polymeric substance such as silk or wool. The electrically conducting material may be prepared by treating the polymeric material with hydrogen sulfide, and then treating the resultant material having adsorbed hydrogen sulfide with (a) a source of ions containing the first metal, (b) a source of ions containing the second metal and, optionally, (c) a sulfur-containing compound to form sulfides of the first and second metals adsorbed by the polymeric material.
