▎ 摘　　要

NOVELTY - Preparing magnetic iron oxide/graphene composite material comprises dispersing graphite oxide into water to obtain oxidized graphite dispersion, then adding iron oxide into oxidized graphite dispersion, carrying out ultrasonic dispersion, then adding ammonia to adjust pH to 12-13, then adding hydrazine hydrate solution, carrying out ultrasonic dispersion for 1-2 minutes, transfer the system into the reactor, reacting at 160-180 degrees C for 10-12 hours, cooling to room temperature, washing and drying to obtain final product. USE - The magnetic iron oxide/graphene composite material is useful for preparing magnetic paint (claimed). ADVANTAGE - The material has excellent dispersibility in paint. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for use of magnetic iron oxide/graphene composite material in preparing magnetic paint.
