▎ 摘　　要

NOVELTY - Preparation of aqueous graphene oxide-modified poly (urethane acrylate) composite material involves preparing oxidized graphite by using improved Hummers method, dissolving obtained product in N,N'-dimethyl formamide in ultrasonic peeling, and obtaining graphene oxide dispersion liquid and then n-butyl acrylate co-modified polyurethane. USE - Preparation of aqueous graphene oxide-modified poly (urethane acrylate) composite material (claimed) used for packaging, furniture, electrical equipment, small metal portions, meter panel, floor, wood, paper, leather, plastic, domestic electrical appliance, electron applications, communication field, aerospace field and aviation field. ADVANTAGE - The method enables preparation of stable and uniform aqueous graphene oxide-modified poly (urethane acrylate) composite material, and provides cured film having excellent mechanical property.
