The graphene nanoplates offered by Strem Chemicals are in a granular form.
Used alone, graphene nanoplatelets can replace both conventional and nanoscale additives while expanding the range of properties being modified.
Used in combination with other additives, they help reduce cost and expand property modification.
With graphene nanoplatelets, you can:
- Increase thermal conductivity and stability
- Increase electrical conductivity
- Improve barrier properties
- Reduce component mass while maintaining or improving properties
- Increase stiffness
- Increase toughness (impact strength)
- Improve appearance, including scratch and mar resistance
- Increase flame retardence
These interesting nanoparticles are comprised of short stacks of platelet-shaped graphene sheets that are identical to those found in the walls of carbon nanotubes, but in a planar form. Hydrogen or covalent bonding capability can be added through functionalization at sites on the edges of the platelets.
Enhanced barrier properties and improved mechanical properties (stiffness, strength, and surface hardness) can be achieved with the graphene nanoplatelets due to their unique size and morphology. The nanoplatelets are also excellent electrical and thermal conductors as a result of their pure graphitic composition.
Graphene nanoplatelets are 6-8 nm thick with a bulk density of 0.03 to 0.1 g/cc, an oxygen content of <1% and a carbon content of >99.5 wt% and a residual acid content of of
