Graphene nanoplatelets are unique nanoparticles consisting of stacks of graphene sheets in a sheet-like form.
We offer: Graphene microsheets, multilayer graphene microsheets, graphitized graphene oxide graphene microsheets.
The unique size and platelet morphology of graphene nanoplatelets make these particles particularly effective in providing barrier properties, while the pure graphite content makes them excellent electrical and thermal conductors.
Graphene nanoplatelets can improve mechanical properties such as stiffness, strength and surface hardness of the host material. Graphene nanoplatelets are compatible with nearly all polymers, can be used as active ingredients in inks or coatings, and are excellent additives for all types of plastics.
Their unique manufacturing process is non-oxidative, so the material has a pristine graphitic surface of sp2 carbon molecules, which is particularly suitable for applications requiring high electrical or thermal conductivity.
C-grade particles are typically composed of submicron flake aggregates with a particle size of less than 2 microns and a typical particle thickness of a few nanometers – depending on the surface area. Typically, C-grade particles have a high surface area and large porosity. C-grade particles are available in different grades with average surface areas of 300, 500 and 750 m2/g.
