What is Graphene?
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.
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.
Graphene powder is globally considered as being a ‘wonder material,’ owing to its impressive properties. It is also known as graphene nanopowder, due to it nano-structural behavior. It is one of the strongest and ideal conductors of heat and electricity. This immensely versatile material is finding increasingly widespread application in research and diverse industries all over the world.
As many researchers believe, graphene floating on the water does not repel water, but attracts it. Graphene is made of the same material as graphite-for example, found in pencils-which is why graphene has long been thought to be as waterproof as gra…
