NOVELTY - Graphene-coated nanocomposite material preparation involves mixing 0.05-0.1 g of nano material in 100-150 ml of deionized water for 20-40 minutes to obtain a solution. 0.005-0.01 g of oxidized graphite alkene is dissolved in 50-60 ml of deionized water via ultrasonic waves for 5-10 minutes for obtaining another solution. The former and the latter solutions are mixed for 1-2 hours for obtaining a mixed solution. The mixed solution is frozen in liquid nitrogen for 30-90 seconds, and then set in a freezing dryer for freezing and drying. USE - Method for preparing graphene-coated nanocomposite material. ADVANTAGE - The method provides grapheme-coated nanocomposite material without damaging a surface characteristic of a material in a simple and cost-effective manner. DETAILED DESCRIPTION - Graphene-coated nanocomposite material preparation involves mixing 0.05-0.1 g of nano-material in 100-150 ml of deionized water for 20-40 minutes to obtain a solution. 0.005-0.01 g of oxidized graphite alkene is dissolved in 50-60 ml of deionized water via ultrasonic waves for 5-10 minutes for obtaining another solution. The former and the latter solutions are mixed for 1-2 hours for obtaining a mixed solution. The mixed solution is frozen in liquid nitrogen for 30-90 seconds, and then set in a freezing dryer for freezing and drying. The dried sample is placed in a muffle furnace at 500-600 degrees C in an inert gas for 2-3 hours to obtain the graphene-coated nanocomposite material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a transmission electric mirror image of the zinc oxide.
