▎ 摘　　要

NOVELTY - Preparing surface metallization material comprises modifying the surface of the oxidation graphene and the carbon nano-tube, mixing uniformly, and reducing graphene oxide to obtain the composite carbon nano-material, mixing the silver ammonia complex ion solution with the modified silver oxide nano-powder coated with poly-dopamine layer on the surface, removing the solvent to obtain the silver-containing composite precursor, and uniformly mixing with the composite carbon nano material, resin, dispersant and solvent. USE - The surface metallization material is useful for mobile phone antenna. ADVANTAGE - The surface metallization material solves the problem of poor compatibility of carbon nano-material and nano-silver particles, has excellent conductive and heat-conducting ability with low thermal expansion coefficient and good mechanical performance, and realizes metallurgical bonding of both. The metal plating layer, metallized carbon nano material, the combination between the middle frame is more compact, and the strength can reach the practical requirement. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: Surface metallization material for mobile phone antenna prepared according to above mentioned method. Mobile phone antenna surface metallization method.
