Abstract
A graphene dispersion paste has a viscosity in a range from 50,000 to 350,000 cps and a scraper fineness less than 20 μm, and includes graphene sheets, a solvent and a first polymer, wherein the graphene sheets have a bulk density in a range from 0.005 to 0.05 g/cm3, a thickness in a range from 0.68 to 10 nm, and a plane lateral dimension in a range from 1 to 100 μm. The present application further provides methods of preparing and using the graphene dispersion paste.
