What are Graphene Nanoplatelets? -GNPs

Graphene nanoplatelets-GNPs consist of small stacks of graphene that can replace carbon fiber, carbon nanotubes, nano-clays, or other compounds in many composite applications. When added in trace amounts to plastics or resins, our graphene nanoplatelets make these materials electrically or thermally conductive and less permeable to gasses, while simultaneously improving mechanical properties like strength, stiffness, or surface toughness.

Our graphene nanoplatelets (GNPs) are useful as nanoscale additives for advanced composites, as a component in advanced batteries and ultra/super capacitors, as the conductive component in specialty coatings or adhesives, and as a component of e-inks or printable electronic circuits.

Other applications include exceptionally strong and impermeable packaging, better lubricants, and a recent publication even demonstrates that our conductive graphene nano-platelets, surface-treated with sensitized molecules, can be used to produce highly sensitive bio-sensors.

Our GNPs consist of several sheets of graphene with an overall thickness of approximately 3-10 nanometers depending on the specific product. Grade 4 GNPs are <4nm thick.
