current interest in conductive plastics has triggered several approaches in utilizing fillers to transform plastics into a higher-strength conductive structure. metal fillers and fibers have been used in polypropylene composites of higher electrical conductivities. recently, attempts have been made to improve the mechanical properties of filled plastics by treating the surface of metal fillers or aluminum alloy flakes with titanate coupling agents. sizing agents based on poly(vinyl alcohol) have been used with stainless-steel microfibers to improve their adhesion to the plastic matrix. spray coating with metals is used to impart surface conductivity to plastics. the mechanical properties of polypropylene depend on its thermal stability and history. it is generally accepted that multivalent ions of metals with very high melting temperatures such as copper, manganese, iron, chromium, cobalt, and nickel catalyze the oxidation of polypropylene. stabilization of polypropylene against active metals, heat, and light has been reported. polypropylene under isothermal heating at 500 degreesc decomposes within only 1 min entirely into volatile materials and low-molecular-weight compounds. the author explores the mechanism and superior properties of the structurally novel conductive composite of an interpenetrated network of tin and zinc metal alloy, prepared by melting the metal alloy in the polypropylene matrix
