▎ 摘　　要

NOVELTY - Nickel oxide and nickel composite graphene coated cotton carbon fiber material preparation involves immersing non-woven cotton in a graphite oxide solution for sonication, and then freeze-drying to obtain graphene-coated non-woven cotton fiber. The nickel chloride is dissolved in an anhydrous ethanol solution, where the graphene oxide-coated non-woven cotton fiber is immersed in the prepared solution, and then taken out and placed in a dry box for drying. A protective gas is passed in the furnace at 600-1100 degrees C for 1-10 hours, and then heated for passing shielding gas. The furnace temperature is lowered to room temperature to obtain the composite graphene coated cotton carbon fiber material. USE - Method for preparation composite nickel oxide and nickel composite graphene coated cotton carbon fiber material. ADVANTAGE - The method prepares the composite nickel oxide and nickel composite graphene coated cotton carbon fiber material in a simple, cost-effective and eco-friendly manner. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic scanning electron microscopic picture of the composite nickel oxide and nickel composite graphene coated cotton carbon fiber material.
