ABSTRACT:
A process is disclosed for making metal plated fibrids wherein the plating is conductive and highly durable. The process involves contacting the fibrids with an 80 to 90% sulfuric acid solution, neutralizing and washing the fibrids with water, and then plating the fibrids by an electroless plating process. The acid treatment of the fibrids promotes adhesion between the metal and the fibrids and promotes high electrical conductivity for the plated metal.
