NOVELTY - A modified aqueous graphene homogeneous layer dispersion comprises 100-200 pts. wt. graphene oxide nanosheet layer dispersion having content of 0.2 wt.% graphene oxide, 5-8 pts. wt. intercalation polymerization monomer, 10-15 pts. wt. comonomer, 0.2-0.5 pts. wt. initiator and 1-2 pts. wt. alkaline substance. USE - Modified aqueous graphene homogeneous layer dispersion for cement-based composite materials. ADVANTAGE - The modified aqueous graphene homogeneous layer dispersion for cement-based composite materials provides cement composite structure with strong ability to resist penetration and crack resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of a modified graphene oxide small-layer aqueous phase uniform dispersion, involves adding 100-200 pts. wt. graphene oxide nanosheet layer dispersion with a mass fraction of 0.2% to the reactor and heating to 50-60 degrees C, adding 5-8 pts. wt. intercalation polymerization monomer, stirring for 1-2 hours, penetrating the intercalated monomer with a permeable dispersion of the cyclic structure into the graphene oxide sheet to enlarge the distance between the sheets to achieve intercalation, and the cyclic intercalation molecule has a graphene oxide active group forming chemical bonds and intermolecular forces, and uniformly fixing intercalated molecules on the surface and interface of the graphene oxide to achieve a template effect, and then adding 10-15 pts. wt. comonomer, 0.2-0.5 pts. wt. initiator, and 1-2 pts. wt. alkaline substance, continue stirring at 50-60 degrees C for 2-3 hours, copolymerizing the intercalation monomer and the comonomer to realize the graft copolymerization of the intercalation monomer and the comonomer, and lowering the temperature to 25-30 degrees C and ultrasonically dispersing for 1-2 hours.
