Graphene Nanoplatelets (GNP) consist of small stacks of graphene that can replace carbon fiber, carbon nanotubes, nano-clays, or other compounds in many composite applications. When they are added at 2-5wt% to plastics or resins they make these materials electrically or thermally conductive and less permeable to gasses, while simultaneously improving mechanical properties like strength, stiffness, or surface toughness. The GNPs that all have the same image are the plasma exfoliated products.
GNPs consist of several sheets of graphene with an overall thickness of approximately 3-10 nanometers depending on the specific product. Graphene Nanoplatelets are friable to 4 layers thick.
