Graphite nanoplatelets, which combine the layered structure and low price of nanoclays with the superior mechanical, electrical, and thermal properties of carbon nanotubes, are very cost-effective, and can simultaneously provide a multitude of physical and chemical property enhancements.
Graphite nanoplatelets particles consist of small stacks of graphene obtained by exfoliation of expanded graphite. The size and morphology of nanoplatelets makes these particles especially effective at providing barrier properties, while their graphene structure makes them excellent thermal and electrical conductors.Unlike many other additives, graphite nanoplateletes improve mechanical properties like stiffness, strength, and surface hardness of the matrix material.
Graphite nanoplatelets improves mechanical properties of most composites, particularly stiffness and tensile strength. Elastomeric compounds have been shown to experience increased life and reduced surface wear when reinforced with graphite nanoplatelets. Particles can be aligned using electric field, although alignment is not necessary for use in most extrusion systems.
Graphite nanoplatelets can also be combined with glass fibers or other matrix materials to provide sufficient conductivity for electrostatic painting or other applications requiring electrical conductivity. Graphite nanoplatelets has a percolation threshold for conductivity of 1.9 wt% in thermoplastic matrix. At densities of 2–5 wt%, conductivity reaches sufficient levels to provide electromagnetic shielding.
Graphite nanoplatelets consist of small stacks of graphene that can replace carbon fiber, carbon nanotubes, nano-clays, or other compounds in many composite applications. When they are added at 2-5wt% to plastics or resins they make these materials electrically or thermally conductive and less permeable to gasses, while simultaneously improving mechanical properties like strength, stiffness, or surface toughness.
