NOVELTY - Producing a graphene suspension comprising isolated graphene sheets dispersed in a liquid medium, comprises: (a) mixing multiple particles of a graphitic material and multiple particles of a solid carrier material to form a mixture in an impacting chamber of an energy impacting apparatus; (b) operating the energy impacting apparatus with a frequency and an intensity for a length of time sufficient for peeling off graphene sheets from the graphitic material and transferring the graphene sheets to surfaces of the solid carrier material particles to produce graphene-coated solid carrier particles inside the impacting chamber; and (c) dispersing the graphene-coated solid carrier particles in the liquid medium and separating the graphene sheets from the solid carrier material particles using ultrasonication or mechanical shearing means and removing the solid carrier material from the liquid medium to produce the graphene suspension. USE - The method is useful for producing a graphene suspension. ADVANTAGE - The method: is strikingly simple, fast, environmentally benign, economical and highly scalable; and reduces the amount of undesirable chemical, shortens the process time, reduces environmental impact and produces graphene suspension directly from graphitic material.
