▎ 摘　　要

NOVELTY - The method involves mixing 25-95 wt.% metal salt oxide graphene and metal salt with ethyl alcohol and ethanediol, where the mixture is added with propylene glycol to form a precursor solution. A flow spray needle is used for spraying the precursor solution. A metal salt solution is added with deionized water. The metal salt is mixed with graphene oxide and maintained at 100-300 degree Celsius for 8-30 hours. USE - Graphene oxide composite material preparation method. ADVANTAGE - The method ensures high capacity, better circulation stability of graphene oxide composite material and low manufacturing cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene oxide composite material. DESCRIPTION OF DRAWING(S) - The drawing shows a graph illustrating a graphene oxide composite material preparation method.
