Metal Foil and Composite Heat Dissipating Plate Thereof |
摘要 |
The present invention provides a highly thermal conductive and heat radiation absorptive metal foil with a basis weight of at least 220g/m2 and a metal content of at least 90%. The present invention further provides a composite heat dissipating plate comprising a metal foil having a first surface and an opposite second surface, a basis weight of at least 220g/m2, a metal content of at least 90%, and at least a layer of nitrogen-doped graphene coated on at least one of the first surface and the second surface. At least one of the above-mentioned surfaces has a roughness of 0.19≦Ra≦0.23 μm, 1.3≦Rt≦1.84 μm and/or 1.02≦Rz≦1.07 μm. The metal foil has crystal size between 308 and 434 Å, and a lightness of surface colors of 25<L*<40. |
