NOVELTY - Preparing a water-based graphene dispersion using shear stabilization involves 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 consist of a surfactant comprising silicone, an organomodified copolymer, and mixtures 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, where 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. USE - Method for preparing a water-based graphene dispersion using shear stabilization used in spray painting, coatings, automotive wax, architectural coating and paint coating. ADVANTAGE - The method enables to prepare a water-based graphene dispersion that is stable without visible phase separation after storage at room temperature for at least one year or even more than one year and has improved thermal conductivity properties DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: 1. a water-based graphene dispersion, which comprises a water dispersible rheology agent, water, graphene platelet particles, and a surfactant that reduces surface tension of the water and selected from the group consist of a surfactant comprising silicone, an organomodified copolymer, and mixtures thereof, wherein the graphene platelet particles have an average thickness of about 1-10 nm and are dispersed homogeneously in the water-based graphene dispersion, and the water-based graphene dispersion is stable without visible phase separation after storage at room temperature for at least 1 month; and 2. a car care product, which comprises water-based graphene dispersion, where car care product further comprises at least one of anionic surfactants, cationic surfactants, non-ionic surfactants, amphoteric surfactants, non-ionic emulsifiers, UV absorbers, mineral oil, butyl cellosolve, fragrances, colorants, preservatives, thickening agents, abrasive polishing agents, neutralizing agents, or stabilizing agents.
