Graphene Nanoplatelets (GNPs)
Our graphene nanoplatelets are useful as nano-additives for advanced composites, as a component in advanced batteries and ultracapacitors, as the conductive component in specialty coatings or adhesives, and as a component of e-inks or printable electronic circuits.
Other applications include exceptionally strong and impermeable packaging, better lubricants, and a recent publication even demonstrates that our conductive graphene nano-platelets, surface-treated with sensitized molecules, can be used to produce highly sensitive bio-sensors.
Our GNPs consist of several sheets of graphene with an overall thickness of approximately 5 nanometers (ranging from 1 nm to 15nm) and particle diameters that can range from sub-micron to 100+ microns.

Grades
Our current materials come in three “grades” and sizes:
1. Grade 1 – has a surface area of about 50 m2/g and an average
thickness of about 15 nanometers. It is available in average sizes of 5, 15,25 micron diameters. This material is good for some thermal applications and also where mechanical sheer forces are extreme.
2. Grade 2 – has a surface area of about 100 m2/g and an average
thickness of a bit less than 10 nanometers. It is available in average
diameters of 5, 15, and 25 microns. This is the standard material that we typically ship to customers unless there is a reason to do otherwise.
3. We also have an “experimental” grade 3, which has surface areas of
600 – 750 m2/g and typical particle diameters of less than 2 microns. This material is actually composed of aggregates of sub-micron sized particles and, because of the small size, the platelet shape is not dominant. This material is very good for applications requiring high capacitance. Currently, we can only make this material in small amounts. The price for this grade is currently set at $15 per gram but will, of course, decrease once we get our higher volume production in place.
