▎ 摘　　要

NOVELTY - A mobile terminal backplane comprises a thermally conductive layer containing graphene and/or graphene oxide, and a thermosetting resin, a reinforcing layer provided on one surface of the thermally conductive layer, and containing glass fiber powder and a thermosetting resin, and a protective layer provided on the surface of the reinforcing layer away from the thermally conductive layer, and containing diamond and a thermosetting resin. USE - Backplane of mobile terminal (claimed). ADVANTAGE - The mobile terminal back plate has simple structure, high hardness, high temperature resistance, excellent flame retardance, bending strength, high relative dielectric constant and shielding ability, and can be manufactured economically by simple method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of mobile terminal backplane.
