The present invention relates to an aqueous graphene suspension comprising: n- a liquid suspension medium comprising more than 50% by weight of water with respect to the total amount of liquid suspension medium, n- at least one graphene material, and n- at least one anionic surfactant with a part thereof being present as functionalizing said graphene material, nwherein the weight percentage of anionic surfactant with respect to the amount of graphene material is at most equal to 100%. n It further relates to a process for preparing an aqueous chemically reduced graphene oxide suspension and to a process for manufacturing a graphene material-polymer nanocomposite, and more specifically a chemically reduced graphene oxide-polymer nanocomposite from an aqueous graphene material suspension, and more specifically an aqueous chemically reduced graphene oxide (CRGO) suspension and monomer(s), said process comprising at least the steps consisting in: n(A) an addition of monomer(s) to a suspension according the present invention, and n(B) a polymerization of said monomer(s) to yield said nanocomposite |
