一般描述

Graphene nanoplatelets are “pure carbon”, 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, or thermoplastics. 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.
