▎ 摘　　要

NOVELTY - Graphite oxide is mixed with ethylene glycol, and ultrasonically-mixed for 1-2 hours, to obtain graphene oxide solution. The volume ratio of graphite oxide and ethylene glycol is 1-4 mg:1-4 mL. Predetermined amount of water is added to graphene oxide solution to form dilute graphite oxide solution, and ultrasonically-mixed for 10-30 minutes. Predetermined amount of liquid stannous chloride is added and ultrasonically-mixed for 10-30 minutes. The liquid mixture is heated in oil bath, to obtain high-dispersibility graphene-loaded tin-dioxide nanoparticles-containing composite material. USE - Preparation of high-dispersibility graphene-loaded tin-dioxide nanoparticles-containing composite material (claimed). ADVANTAGE - The method enables preparation of high-dispersibility graphene-loaded tin-dioxide nanoparticles-containing composite material by simple method, without agglomeration. DETAILED DESCRIPTION - Graphite oxide is mixed with ethylene glycol, and ultrasonically-mixed for 1-2 hours, to obtain graphene oxide solution. The volume ratio of graphite oxide and ethylene glycol is 1-4 mg:1-4 mL. Predetermined amount of water is added to graphene oxide solution to form dilute graphite oxide solution, and ultrasonically-mixed for 10-30 minutes. Predetermined amount of liquid stannous chloride is added and ultrasonically-mixed for 10-30 minutes. The volume ratio of stannous chloride and water is 10-50 mg: 1 mL. The mass ratio of stannous chloride and graphite oxide is 1:2-4. The liquid mixture is heated in oil bath, to obtain high-dispersibility graphene-loaded tin-dioxide nanoparticles-containing composite material.
