▎ 摘 要
NOVELTY - A modified graphene oxide dispersion is prepared by dispersing graphene oxide in amino sugar. USE - Modified graphene oxide dispersion for preparation of paint e.g. silicate aqueous paint (claimed). ADVANTAGE - The modified graphene oxide dispersion has high dispersion stability due to use of amino sugar having highly active amino functional groups which modifies the graphene oxide and improves the dispersion performance of graphene oxide in water. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the modified graphene oxide dispersion, which involves dissolving amino sugar in solvent, stirring to obtain amino sugar solution with concentration of 0.1-10 wt.%, adding graphene oxide to the amino sugar solution and dispersing.
