NOVELTY - Ceramic material precursor alcohol salt, macromolecular polymer, acid additive and volatile solvent are stirred to obtain ceramic nanofiber static spinning solution. The obtained spinning solution is spun, and obtained ceramic/macromolecule composite nanofiber (1 mg to 20 g) is immersed in a volatile solvent to prepare solution (a). Graphene oxide is added into solution (a), and stirred. The obtained solution (a) is subjected to hydrothermal or solvent heat reaction at 90-200 degrees C for 4-48 hours to obtain graphene oxide/ceramic nanoparticle composite material. USE - Manufacture of graphene oxide/ceramic nanoparticle composite material. ADVANTAGE - The method efficiently provides graphene oxide/ceramic nanoparticle composite material by simple method. DETAILED DESCRIPTION - Ceramic material precursor alcohol salt, macromolecular polymer, acid additive and volatile solvent are stirred at 20-90 degrees C for 2-24 hours at the stirring speed of 50-500 rpm/minute to obtain ceramic nanofiber static spinning solution. The macromolecular polymer is polyvinylpyrrolidone or vinyl alcohol. The concentration of macromolecular polymer, additive and ceramic precursor alcohol salt in the reaction system is 10-100 mg/ml, 1-10 mg/ml and 0.1-0.5 g/material, respectively. The acid additive is glacial acetic acid or salt acid. The solvent is ethanol, water or isopropyl alcohol. The obtained spinning solution is spun at 10-40 degrees C with humidity of 10-80% in the spinning voltage of 5-35 kV, flowing rate of 0.1-10 mL/hour and spinning receiving distance of 5-35 cm to obtain ceramic/macromolecule composite nanofiber. Ceramic/macromolecule composite nanofiber (1 mg to 20 g) is immersed in a volatile solvent to prepare a solution (a). The volatile solvent is ethanol, water or isopropyl alcohol. Graphene oxide is added into solution (a), and stirred using a glass rod, such that mass ratio of graphene oxide with respect to nano composite fiber is 100:1-1:100. The obtained solution (a) is added to a hydrothermal kettle, and hydrothermal or solvent heat reaction is performed at 90-200 degrees C for 4-48 hours to obtain graphene oxide/ceramic nanoparticle composite material. The obtained composite material is centrifuged from the reaction solution, and dispersed in water. A reducing agent chosen from sodium borohydride and hydrazine hydrate, is added to the resultant mixture, and processed at 20-100 degrees C for 1-48 hours.
