▎ 摘  要

NOVELTY - Graphene heat conducting paste comprises 1-10 pts. wt. graphene, 0.5-3 pts. wt. anti-settling agent, 0.5-5 pts. wt. adhesive and 82-98 pts. wt. N-methylpyrrolidone, where the anti-settling agent is graphene aerogel. USE - Used as graphene heat conducting paste. ADVANTAGE - The paste: has improved heat conducting coefficient, adhesive force, flexibility, simple process, easy construction, strong adhesion and excellent heat dissipation effect; and uses graphene which can forms continuous heat conduction network inside the film layer to exhibit excellent heat conduction. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene heat conducting paste comprising (i) adding adhesive into N- methylpyrrolidone, and stirring uniformly to obtain mixed solution, (ii) adding graphene, graphene aerogel and anti-settling agent into the mixed liquid, and (iii) stirring mixed liquid using high shear disperser at a speed of 1000-8000 revolutions/minute for 1-10 hours to obtain stable dispersion of final product.
