The preparation of three dimensional(3D) graphene hydrogels is mostly concentrated on the centimeter scale and solid symmetrical structures while the contradiction between small size and low density exists. The graphene mini-motor constructed by the combination of shear-driven aggregation and capillary force induced drying followed by high temperature reduction using graphene oxide suspension as the precursor and aniline as the crosslinking agent. The graphene mini-motor shows ethanol-driven motion and oil adsorption performance because of its small size(about 2~5 mm in diameter), low density(about 0.2~0.7 g/cm3), hollow structure and hydrophobic oleophilicity. It is found that the fastest speed of ethanol-driven rotation can reach 3 r/s, and the saturated adsorption capacity is 794.9 mg/g.
