NOVELTY - Preparing graphene aerogels arranged in a circular flow comprises (S1) providing the graphene oxide sample into a beaker, and adding deionized water, (S2) placing the beaker at a low temperature and performing constant temperature ultrasonic dispersion to obtain a uniform dispersion, (S3) adding an aqueous ammonia solution to the dispersion to adjust the pH of the dispersion, (S4) adding reducing agent VC to the dispersion, (S5) transferring the dispersion to a hydrothermal kettle, and placing in an oven for directional reduction, and (S6) freeze drying the wet gel. USE - The method is useful for preparing graphene aerogels arranged in a circular flow. ADVANTAGE - The method reduces the thermal resistance of the graphene aerogel thermally conductive network, and improves its comprehensive thermal conductivity capability as a thermally conductive filler.
