The invention provides a graphene radiation material, which comprises more than one layer of graphene radiation film. Each graphene radiation film comprises a support layer, a graphene layer and a bonding layer, which are combined with one another, wherein the graphene layer is positioned between the support layer and the bonding layer, and comprises more than one layer of graphene or graphene composite material with a mono-molecule thickness. The invention also provides a preparation method for the graphene radiation material and the use of the graphene radiation material. The material has a high heat-conducting property; and by the material, the radiation effect of an electronic product can be improved, the temperature of the electronic product can be reduced, the use comfort of a user can be improved, the reliability of the electronic product can be improved, and the service life of the electronic product can be prolonged. The graphene radiation films have remarkable cooling effects; and moreover, an industrial preparation method can be adopted, so that cost is greatly decreased, and automatic production is realized. The graphene radiation material can be widely applied to equipment such as smart phones, tablet personal computers, notebooks and the like with small spaces and high radiation requirements.
