NOVELTY - Silicon dioxide nanosphere/graphene composite material comprises amorphous silicon dioxide (SiO2) nanospheres which are closely attached to the graphene, and the diameter of the SiO2 nanospheres is between 150-250 nanometer (nm). USE - Silicon dioxide nanosphere/graphene composite material. ADVANTAGE - The silicon dioxide nanosphere/graphene composite material uses raw materials used are at low cost, and is easy to operate, consists of less steps, requires simple equipment as well as is feasible for industrialized production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing silicon dioxide nanosphere/graphene composite material, which involves: (A) measuring 30mL of ethanol and 3mL of deionized water and mix them thoroughly to prepare an ethanol/water mixed solution; (B) adding 30mg of graphite oxide to the ethanol/water mixed solution; (C) adding 25mg of surface-active agent, i.e., sodium dodecyl benzene sulfonate, and thus obtain the mixed reaction liquid A; (D) placing the mixed reaction liquid A in the ice bath at the temperature of 0 degrees C to conduct ultrasonic treatment until the graphite oxide in the mixed reaction liquid A is completely dissolved, and thus obtain the mixed reaction liquid B; (E) measuring 25mL of tetraethyl orthosilicate, then, slowly dropwise add it into the mixed reaction liquid B; (F) adding 3mg of NaOH, and conduct ultrasonic treatment for 15 minutes, and thus obtain the mixed reaction liquid C; (G) stirring the mixed reaction liquid C with a magnetic stirrer for 2 hours; (H) transferring the mixed reaction liquid C after fully stirred to the lining of a reaction kettle with 1OOmL of polytetrafluoroethylene, and conduct high-temperature reaction at the temperature of 160 degrees C for 12 hours; (I) making the reaction kettle cool to the room temperature; (J) stirring the obtained black product with ethanol, and complete centrifugation as well as rinse it; and (K) drying it at the temperature of 600 degrees C for 12 hours, and thus obtain the target product, i.e., SiO2 nanosphere/graphene composite material.
