Abstract
Abstract Porous metal coated, ultrafine porous polymer articles and a process of producing such coated polymer articles are described. These materials may be prepared by incorporating an organic salt additive into a solid body of a crystalline thermoplastic polymer at a temperature of at least in the melting temperature range of the polymer to form a composite body, cooling the composite body until it solidifies, leaching out the salt additive to produce a polymeric body having an ultrafine porous structure, and treating at least one surface of the polymeric body with an electroless plating procedure whereby a porous metal coated, ultrafine porous polymer article is formed.
