Abstract

The invention discloses a graphene-metal composite material and a preparing raw material, method and application thereof. Firstly, graphene is evenly scattered in single metal aluminum or copper in anano scattering manner, and a prefabricated ingot in which graphene is evenly scattered, and later usage is convenient is prepared; the prefabricated ingot and a metal material comprising one or moremetal components are evenly fused through a co-smelting and stirring manner, and the graphene-metal composite material excellent in heat conduction and heat dissipation efficiency and high in mechanical strength is prepared. The graphene-metal composite material is applied to heat conduction and heat dissipation elements of electronic products, and the problems that heat emitting of the electronicproducts is serious, the electric quantity is used rapidly, shutdown is automatic, operation is in failure, the service life of a battery is shortened, online business operation is slow, and potential safety hazards exist can be effectively solved.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a graphene-metal composite material and its preparation raw material, method and application. Background technique [0002] With the rapid development of modern technology, electronic products tend to be small, thin, light, and multi-functional, which also makes electronic components more miniaturized, the main frequency of chips continues to increase, and the power consumption of a single chip gradually increases. These changes As a result, the heat flux density increases sharply, electronic products heat up severely, and then there are a series of problems such as excessive power consumption, automatic shutdown, operation failure, reduced battery life, slow online business operations, and potential safety hazards. More studies have shown that more than 55% of electronic products fail in the form of overheating, so the heat dissipation of electronic components plays a pivotal ...
