Many non-conductive engineered materials, including organic or inorganic powders, fibers, films, foams and even bulk materials, are used as substrates and effectively coated with a thin layer of polypyrrole (PPy) by the so-called in-situ polymerization of pyrrole monomer. Subsequently, a layer of conductive copper sulfide (CuS) as a top coat is applied to the above PPy-coated substrates by the electroless plating so as to render them electrically conductive on their surfaces. It is critical and useful that PPy is able to facilitate the electroless plating of CuS on its surface with enhanced adhesion, which results in a CuS/PPy coating system having stable electrical conductivity even under the condition of a high temperature (up to 200 C.) for a prolonged time.
