NOVELTY - An enhanced thermal stability hydrophobic functionalized graphene oxide hybrid nanomaterial. USE - Enhanced thermal stability hydrophobic functionalized graphene oxide hybrid nanomaterial for paper making, painting, printing, dyeing, and producing heat-resistant flame retardant polymer nanocomposite. ADVANTAGE - Enhanced thermal stability hydrophobic functionalized graphene oxide hybrid nanomaterial is difficult to disperse in water. Preparation process is simple to operate. DETAILED DESCRIPTION - An enhanced thermal stability hydrophobic functionalized graphene oxide hybrid nanomaterial of formula (I). An INDEPENDENT CLAIM is included for preparation of enhanced thermal stability hydrophobic functionalized graphene oxide hybrid nanomaterial which involves (a) preparing graphite oxide by using natural crystalline flake graphite oxide powder; (b) dissolving graphite oxide in dimethylformamide (DMF) by ultrasonication to obtain 7.5-15 mg/ml graphene oxide-DMF suspension; (c) preparing 2,3-dihydro-3-hydroxyanthranilic acid (DHAA) dehydrogenation solution in which ratio of DMF:DHAA is 50:1-5:1 mg/ml; (d) mixing obtained DHAA dehydrogenation solution:graphene oxide-DMF suspension with ratio of 10:1-1:10, heating, stirring; and (e) filtering under reduced pressure, washing, and drying. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram of preparing enhanced thermal stability hydrophobic functionalized graphene oxide hybrid nanomaterial.
