NOVELTY - Graphene-ferric oxide composite preparation involves weighing graphite oxide and ferric salt in a mass ratio of 1:1-1:100 at room temperature. The weighed materials are mixed with 98-99.5 wt.% of glycol. Polyethylene glycol and anhydrous sodium acetate are also added to the mixture. The obtained mixture is stirred and then heated in a kettle at 180-220 degrees C for 8-16 hours. The obtained product is washed with deionized water and then heated to obtain the desired product. USE - Method for preparing graphene-ferric oxide composite powder (claimed). ADVANTAGE - The method enables large scale graphene-ferric oxide composite production in a simple manner. The prepared graphene-ferric oxide composite is pure crystal and has good dispersibility and high magnetization intensity.
