Description générale

Graphene nanoplatelets are “pure carbon” very lipophilic, with a high tendency to aggregate and poor interactions with the surrounding matrix, hence difficult to disperse in processes and supports such as epoxy resin, thermoplastics or solvents such as water. The chemical modification on the surface of graphite nanoplatelet open new properties allowing good interaction with the targeted matrix. Without these chemical modifications the dispersion step became a difficult task and quite often do not produce the expected benefits.
