Graphene Nanoplatelet catalyst additives are high purity, low defect, ultra-thin particles of graphite of nanometer scale thickness. They can be thought of as short stacks of graphite sheets. This unique powder material breaks down to its primary particle size of a few nanometers upon shearing (nature of the solvent used for shearing and final concentration are the key parameters).

The Graphene Nanoplatelets powder is compatible with all polymers and can be an active ingredient in inks or coatings for fuel cells, electrolyzers, and various other applications. The unique size and platelet morphology of Graphene Nanoplatelets makes these particles especially effective at providing barrier properties, while pure graphitic composition makes them excellent electrical and thermal conductors. Unlike many other additives, Graphene Nanoplatelets can improve mechanical properties such as stiffness, abrasion resistance, and surface hardness of the matrix material.
