▎ 摘 要
NOVELTY - This utility new type relates to a transmission technology field of electric device, especially relates to a new one of composite heat-conducting material, having a layered structure thereof, comprise first metal heat-conducting layer, second conducting layer and first metal the graphene layer, a composite heat-conducting material by a first metal conducting layer one side a outer in turn is second metal conducting layer and first graphene. This utility new type not only has metal of toughness and also has graphene material of good heat-conducting property.
