Claim 0:
1. A method of preparing a water-based graphene dispersion using shear stabilization, the method comprising:
forming an aqueous mixture comprising water, a graphene powder, and a water dispersible rheology agent, and the aqueous mixture further comprises a surfactant that reduces surface tension of the water and selected from the group consisting of a surfactant comprising silicone, an organomodified copolymer, and mixtures thereof; and
shearing the aqueous mixture to break down the graphene powder into graphene platelet particles and to disperse the graphene platelet particles to form the water-based graphene dispersion,
wherein the graphene powder has a first number of graphene layers, the graphene platelet particles dispersed in the water-based graphene dispersion has a second number of graphene layers, and the second number is smaller than the first number.
