Graphene Powder, popular research material

High quality dry powder ready for re-dispersion

Graphene is an extremely popular material within scientific research. When a simple method of exfoliating single layers of graphene from bulk graphite was discovered in 2004, it marked the start of the 2D materials era. 

The properties of single layers were found to be drastically different from those of the bulk material. Many of these properties exceeded those of any known material. Today, graphene is still proving to be one of the most exciting materials around. Since the start of 2018, there have already been 27,000 publications on graphene worldwide. 

Ossila provides 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. The existence of graphene has been well-known for a long time, with TEM images of multi-layer graphene structures being taken as early as the 1940's. However, research into this material only properly began in 2004, when a simple method for isolating single layers of graphene was discovered. Graphene is the constituent material of several forms of carbon materials - including graphite, carbon nanotubes, and fullerenes. 

Initial work on graphene showed that its properties 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 Guide

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).
