Title: The research of the metallization of nonmetal materials
Abstract With the advancement of science and technology, the metallization of nonmetal materials have received tremendous attention in the research of new materials and the applications fields of that extend continuously, such as meet beautiful decoration and some special function of anti-static or anti-electromagnetic shielding. The method of ultrasonic electroless plating of polyurethane foam and glass fiber was used in this paper .The nickel-plated reticulated PUF are even and have high conductivity and good adhesion, which make them a broader range of applications. The concrete research is as follows:
The optimal conditions of electroless plating nikel were obtained by orthogonal experiments and single factor,The Ni-coated PUF was characterized by XRD, SEM, TG, thermal conductivity measurement and thermal shock tests.
Key words: Non-metallic material, PUF, Electroless plating
