NOVELTY - The method involves taking cellulose to disperse in deionized water to obtain cellulose dispersion liquid. The metal salt powder is taken to disperse in deionized water to obtain metal salt dispersion liquid. The cellulose dispersion liquid is mixed with the metal salt dispersion liquid to obtain a mixed liquid. The mixed liquid is dried to obtain mixed powder of cellulose and metal salt. The discharge machining on the mixed powder of the cellulose and the metal salt are performed to prepare the graphene-based high-entropy alloy material. The five metal salt powders are dispersed in deionized water, and the five metal salt powders are ferric chloride, cobalt chloride, nickel chloride, copper chloride and zinc chloride. USE - Method for preparing graphene-based high-entropy alloy material. ADVANTAGE - The method prepares graphene-based high-entropy alloy material which is fast, large area for preparing, and provides high efficiency, stable performance, and high thinning crystal grain when cooling and crystallizing, and improves the structure of the material. The method is simple, and produces large amount of product in a short time, and produces high-quality graphene nano sheet.
