Abstract

A water-based graphene dispersion is made by shear stabilization. The method of preparing the water-based graphene dispersion using shear stabilization includes adding a composition containing a graphene powder, a super wetter surfactant and a water dispersible rheology agent into water to form an aqueous mixture; and shearing the aqueous mixture under high pressures to break down the thick layers of the graphene powder to thin layers of graphene platelet particles and to form the water-based graphene dispersion with the graphene platelet particles dispersed in the water-based graphene dispersion. The water-based graphene dispersion is stable without visible phase separation after storage at room temperature for at least one year or even more than one year.
