▎ 摘　　要

NOVELTY - The preparation method of graphene oxide/ionic liquid nanocomposite material involves adding alkaline compound to aqueous ionic liquid, adjusting the pH value of the ionic liquid aqueous solution to 8-14, mixing graphene oxide and water, and removing water in the mixed solution. The method is used for preparing flowable liquid graphene oxide/ionic liquid nanocomposite and non-flowable soft solid state and hard solid graphene oxide/ionic liquid nanocomposite material. The mass ratio of graphene oxide to ionic liquid in the composite material is 9999:1-1:9999. USE - The method is useful for preparing graphene oxide/ionic liquid nanocomposite material. ADVANTAGE - The method enables preparation of graphene oxide/ionic liquid nanocomposite material with excellent plastic deformation capability and processability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene oxide/ionic liquid nanocomposite material prepared by the method.
