▎ 摘 要
NOVELTY - Graphene composite gel preparation involves dispersing graphene oxide in a dispersion liquid. The obtained mixture is added with ethylene diamine and iron oxide. The obtained mixture is heated on water bath. The obtained mixture is frozen. The obtained frozen mixture is dried. The obtained mixture is kept in a microwave. USE - Method for preparing graphene composite gel (claimed). ADVANTAGE - The method enables to prepare graphene composite gel in an eco-friendly and cost-effective manner, and has good absorbing effect.
