NOVELTY - Preparing MXene/graphene/polyvinyl alcohol composite gel, comprises (i) mixing MXene dispersion and graphene oxide dispersion, and carrying out hydrothermal reaction to obtain MXene/graphene composite gel, and (ii) soaking MXene/graphene composite gel in polyvinyl alcohol solution to form hydrogen bond between molecules, freezing and thawing for multiple times to obtain final product. USE - The method is useful for preparing MXene/graphene/polyvinyl alcohol composite gel. ADVANTAGE - The method: utilizes irregular MXene as intercalator, which reduces aggregation between graphene sheet layers and makes the composite gel to exhibit stable electrochemical performance; has simple process, and mild reaction conditions; and adopts hydrogen bonding interaction between polyvinyl alcohol and MXene to enhance the elastic properties of the obtained composite gel. The composite gel has excellent compression recovery performance.
