DETAILED DESCRIPTION - Manufacturing carbon nano ink, comprises: (a) providing fusion-type carbon nanomaterial by mixing control-type carbon nanomaterial having a controlled length of 1-3 mu m and linear carbon nanomaterial in graphene; and (b) dispersing a solvent with a dispersing agent (0.5-2 times the concentration of carbon nanomaterial) and control-type carbon nanomaterial and/or fusion-type carbon nanomaterial in a weight ratio of 0.1-20 wt.%. The step (a) further comprises loading graphene and linear carbon nanomaterial into a ball milling device, mixing the contents at a low speed, and ultrasonically dispersing comprising dispersing between planar graphene layer and linear carbon nanomaterial with separation layer of graphene at high speed, and mechanically milling graphene and linear carbon nanomaterial in solvent. An INDEPENDENT CLAIM is also included for activation of carbon nano-coating for heat dissipation, comprising: coating the carbon nano ink onto a nanomaterial and curing to form carbon nanotube coating layer; and exposing the tip end of the carbon nanomaterial from the carbon nanotube coating layer.
