NOVELTY - Preparing metal oxide graphene composite wave-absorbing material involves placing graphene oxide, 1-2.5 pts. wt. dispersant, 1000-1500 pts. wt. water into reaction kettle. The temperature is controlled at 40-55 degrees C. The high-speed stirring is carried out for 30-40 minutes. The 1-5 pts. wt. nickel nitrate, 10-15 pts. wt. cerium nitrate, 0.01-0.2 pts. wt. 4-chlorophenyl zinc iodide, 0.01-0.5 pts. wt. dilithium tetrabromonickelate, 0.01-0.2 pts. wt. 3-amino-4(3H)-quinazolinone and 0.01-0.1 pts. wt. dichlorotetrakis(pyridine) iron are added to reaction vessel, stirred and dissolved. The pH is adjusted to 11-12 with sodium hydroxide solution under high-speed stirring. The 100-150 pts. wt. hydrazine hydrate is added and mixed well. The material is transferred to hydrothermal reaction kettle, heated at 150-180?OC for 4-6 hours. The material is cooled, filtered, washed, and dried under nitrogen protection. USE - Method for preparing metal oxide graphene composite wave-absorbing material. ADVANTAGE - The method enables to prepare metal oxide graphene composite wave-absorbing material that has strong absorption and improves conductivity of graphene. DETAILED DESCRIPTION - The temperature is raised to 500 degrees C for 3-5 hours to obtain metal oxide graphene composite wave-absorbing material.
