Abstract: The invention relates to a method of producing a suspension of graphene particles and the corresponding suspension. The method of producing a suspension of graphene particles comprises the steps of: [a] depositing carbon on a substrate by means of CVD, where graphene particles are formed on the substrate partially covering it, [b] interrupting the deposition of carbon on the substrate before the surface of the substrate coated with graphene is more than 85% of the total surface of the substrate, [c] immersing the substrate in a liquid, and [d] separating the graphene particles from the substrate such that they are suspended in the liquid. At least 50% of the graphene particles in the suspension are monolayer particles.
