NOVELTY - Heat dissipation ink comprises 96.52-97.54 wt.% ink material, 1.63-2.65 wt.% graphene, 0.12-0.42 wt.% carbon nanotubes and 0.32-0.74 wt.% carbon black. USE - The heat-dissipating ink useful in manufacturing process of circuit board of electronic product. ADVANTAGE - The ink material with radiating heat-conducting performance of the graphene nano-tube, the heat generated by the chip and the printed circuit board (PCB) board can be absorbed to the ink coating, and then the heat is dispersed to the air, the radiating performance of traditional ink is improved.
