▎ 摘　　要

NOVELTY - Mobile terminal backplane comprises heat conductive layer (100), which contains one of graphene or graphene oxide, and thermoplastic resin and protective layer (200), which is disposed on one surface of heat conductive layer, and the protective layer contains diamond and thermoplastic resin. USE - Mobile terminal backplane used in mobile terminal (claimed). ADVANTAGE - The mobile terminal backplane has simple structure, high yield, low cost, large toughness, high damage tolerance, high relative dielectric constant, strong anti-signal shielding ability, good shock resistance, and improves problem of mobile terminal in the protecting layer. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a mobile terminal comprises mobile terminal backplane; and (2) a method for preparing mobile terminal backplane, which involves subjecting all raw materials of heat conductive layer to first extrusion treatment to obtain a first sheet; subjecting all raw materials of protective layer to second extrusion treatment to obtain a second sheet; and subjecting obtained first sheet and second sheet to hot press forming to obtain final product. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of mobile terminal backplane. Heat conductive layer (100) Protective layer (200)
