NOVELTY - Preparation of a solid liquid interface self-assembly comprises carrying out ultrasonic oscillation at 120-300 W for 2-10 hours of a graphite oxide powder and deionized water at a ratio of 7:7-1 to obtain a graphene oxide aqueous solution; soaking porous anodized aluminum thin film or aluminum sheet, aluminum foil or copper sheet processed by a mixed liquid of 98% concentrated sulfuric acid and hydrogen peroxide at a volume ratio of 3:1 in 1-7 mg/mL graphene oxide aqueous solution at 0-80 degrees C for 4-168 hours; and forming graphene aquagel on the surface of the porous anodized film or sheet. USE - Method for the preparation of a solid liquid interface self-assembly (claimed). ADVANTAGE - The method is simple, does not require high temperature and high pressure process, and the water content of the graphene aquagel is more than 99%.
