▎ 摘　　要

NOVELTY - A monolithic graphene oxide/polyethylene glycol monomethyl ether methacrylamide aqueous composite material contains 0.1-0.4 wt.% monolithic oxidized graphene aqueous phase dispersion and 1-4 wt.% polyethylene glycol monomethyl ether methacrylamide aqueous solution. USE - Graphene oxide/polyethylene glycol monomethyl ether methacrylamide aqueous composite material is used as cement mortar and cement concrete additive (all claimed). ADVANTAGE - The product formed using the cement concrete comprising the graphene oxide/polyethylene glycol monomethyl ether methacrylamide aqueous composite material has excellent durability, strength and toughness, high brittleness, and reduced degradation rate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of monolithic graphene oxide/polyethylene glycol monomethyl ether methacrylamide aqueous composite material, which involves preparing monolithic graphene oil aqueous dispersion and polyethylene glycol monomethyl ether methacrylamide aqueous solution with deionized water at 25 degrees C, adding pre-formulated monolithic graphene aqueous phase dispersion to reactor, starting mechanical mixing device, dripping polyethylene glycol monomethyl ether methacrylamide aqueous solution, vigorously stirring mixture and uniformly mixing mixture.
