Abstract
An air flow generating device, a graphene dispersion, and a preparation method thereof are provided. The graphene dispersion is formed by a graphene powder and a processing solvent, wherein the graphene in the graphene dispersion has an average diameter of 0.5 μm to 1 μm, 3 to 5 layers, a solid content of 5% to 50%, and a residue oxygen content less than 1 wt %, and after being left to stand for 12 hours, the graphene dispersion has a distribution concentration increasing from the top section to the bottom section of the storage container, a viscosity of 5000 cps to 8000 cps, and a graphene concentration of 20 wt %.
