NOVELTY - Hollow bowl-shaped graphene oxide micro-motor is claimed. The micro-motor is asymmetrical three-dimensional hollow bowl-type structure, and the average diameter is 30-1.5 mm. USE - Used as hollow bowl-shaped graphene oxide micro-motor. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing hollow bowl-shaped graphene oxide micro-motor comprising (i) preparing graphene oxide, (ii) ultrasonically dispersing prepared graphene oxide into water at room temperature to prepare suspension of 2-10 mg/ml, then adding manganese ferrite (MnFe2O4) powder into the suspension, and ultrasonically forming a uniform suspension, the ratio between suspension and manganese ferrite powder is 10:5-80 (ml:mg), then adding aniline solution dropwise, adding 200-5 ml per 10 ml of suspension, stirring the mixture by a motorized mixer with a rotation speed of 50-2800 revolutions per minute until the mixture is changed from a uniform suspension to a flocculent precipitate, and recovering the precipitate, and (iii) drying the precipitate at room temperature to obtain final product.
