Introduction
Graphene nanoplatelets with an average thickness of the 5 – 10 nanometers are offered invarying sizes up to 50 microns. 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.
