▎ 摘  要

NOVELTY - Preparation method of graphene/carbon nanotube composite aerogel with high-efficiency oil-absorbing performance comprises ultrasonically dispersing graphene oxide in deionized water for 1 hour, obtaining graphene oxide dispersion liquid, mixing carbon nanotube with the graphene oxide dispersion liquid, ultrasonically dispersing to obtain graphene oxide/carbon nanotube dispersion liquid, adding polyvinylpyrrolidone, polyvinyl alcohol, and ethylene diamine, stirring uniformly, putting into a hydrothermal kettle at 120 degrees C, reacting for 12 hours to obtain graphene/carbon nanotube product, dialyzing in deionized water, immersing in ethanol solution, taking out and freeze-drying for 48 hours. USE - Preparation method of graphene/carbon nanotube composite aerogel. ADVANTAGE - The method provides graphene/carbon nanotube composite aerogel with high-efficiency oil-absorbing performance and good elasticity and mechanical strength.
