▎ 摘　　要

NOVELTY - Preparing 3D polyaniline/graphene aerogels composite oil-absorbing material with high adsorption activity, comprises adding graphene and polyaniline into water, ultrasonically dispersing evenly to obtain solution A, where the mass ratio of graphene to polyaniline is 6:1-6, adding the solution A into hydrothermal reactor, carrying out hydrothermal reaction at 150 degrees C for 24 hours, and freezing for 12 hours, freeze-drying in a freeze dryer for 48 hours. USE - The method is useful for preparing 3D polyaniline/graphene aerogels composite oil-absorbing material with high adsorption activity (claimed). ADVANTAGE - The oil-absorbing material has simple synthesis process and low cost, and can adsorb oil matter at normal temperature. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for 3D polyaniline/graphene aerogels composite oil-absorbing material with high adsorption activity, prepared as mentioned above.
