▎ 摘 要
NOVELTY - This invention discloses a thermally conductive composition which consists of grapheme powder and a solvent. The percentage of the grapheme powder in the thermally conductive composition is 70-90 wt%, and the solvent of the composition is selected from silicone oil or octadecane. The thermally conductive composition can be used as a thermal paste for high wattage LED substrate.
