Graphene Powders

Graphene is one of the most popular materials within research. The initial discovery of a simple method to exfoliate single layers from bulk graphite in 2004 heralded the start of the era of 2d materials. It was discovered that properties of single layers differed drastically from those of the bulk material. Many of these properties exceeded those of any known material and even today graphene is still proving to be one of the most exciting materials around. In 2015 alone there were nearly 22,000 publications on graphene from around the world. 

At Ossila we sell several forms of graphene powder; including monolayer flakes, multilayer flakes, and nanoplatelets. Each of these powders can be dispersed using our recommended solvents or dispersion guides for quick use.

What is Graphene?

Graphene is a hexagonal lattice of carbon atoms that spread to form a single sheet in 2 dimensions, there is no limit to the size that graphene sheets can become. Graphene is the constituent material of several forms of carbon materials including graphite, carbon nanotubes, and fullerenes. The existence of graphene has been well know for a long time with TEM images of multi-layer graphene structures being taken as early as the 1940's. However, it was not until the discovery of a simple method for isolating single layers of graphene was discovered in 2004 that research into this material began in earnest.

Initial work on graphene showed that it had properties that vastly exceeded those of the bulk graphite that it was taken from. Properties such as the strength showed that a single layer of the material was over 200 times stronger than steel; the mobility of both holes and electrons were comparable to that of bulk metals such as copper; the thermal conductivity is so high as to be considered ballistic without impedance from the material itself; and single layers have a high opacity with over 2% of light at the near infrared being absorbed.

All of these unique properties mean that graphene could find use in a wide variety of applications including electrochemical capacitor devices, anti-corrosion coatings, composite materials, transparent conducting films, thermal pastes, as well as sensing and biosensing applications.

Dispersion Guides

Graphene is hydrophobic, making it difficult to create stable dispersions in most solvents. At Ossila, we have found that the most stable dispersions can be produced using the following recipe:

  • Weigh out desired amount of graphene powder, can go up to 0.1
  • Add 3:2 ratio of isopropyl alcohol to ethylene glycol.
  • Shake vigorously to break up material.
  • A 2 hour treatment in an ultrasonic bath will homogeneously disperse the material (40 kHz, 100 W ultrasonic bath).
