Summary:Process for obtaining an uniform dispersion of graphene platelets in a liquid by using a base paste that comprises carbon nanofibers in the form of dry powder and a structure having a continuous helical graphitic ribbon developing a spiral around and along the main axis of each of the carbon nanofibers, where said ribbon comprises a stacking of a small number of graphitic layers, intercalant powder and ligand liquid to obtain a uniform dispersion of graphene platelets in a liquid. This base paste is subjected to a fragmentation, intercalation and exfoliation stage, the subsequent addition of a liquid and finally a physical process to obtain a uniform dispersion of graphene platelets in order to homogenise and stabilise the dispersion.
