▎ 摘　　要

NOVELTY - Preparing graphene electromagnetic shielding heating slurry carbon nano-tube comprises (i) dispersing a small amount of graphene and carbon nano-tube in a solvent and performing ultrasonic stripping treatment to obtain mixed solution of graphene carbon nano-tubes, (ii) adding carbon black, metal salt and dispersant into the graphene carbon nanotube mixed solution to obtain mixed solution, and (iii) mechanically dispersing at high speed for two hours to obtain final product. USE - The method is useful for preparing graphene electromagnetic shielding heating slurry carbon nano-tube. ADVANTAGE - The nano-tube: has shielding effect of 70 dB or more in 1.5-10 GHz, and excellent heating effect.
