RS Mines and Graphene

With the emergence of graphene in 2010, courtesy of Sir Andre Geim and Sir Novoselov, who essentially bought a spot light to the work executed by previous scientists, most noteworthy being, Brodie - 1859 and 1957 - Hummers and Offeman.

Since the Nobel Prize being awarded to Sir Geim and Sir Novoselov in 2010, graphene has sparked mass study, vast investment into R&D - scale-up.

During the course of graphene's race to market, scientists and industrialists have realised the hurdles in getting graphene to the consumer market, however with all the criticism and doubt, we are now starting to see graphene integrate an disrupt products and markets.

And this is the just the beginning...

In 2013 RS Mines made it's first breakthrough in graphene via plasma (definition & image) specialist, Haydale of the United Kingdom, through their split plasma technology, created an excellent grade of Graphene Nano Platelets (GNPs), Haydale's conclusion was that RS Mines 99%+ natural crystalline vein graphite had very few defects, was highly crystalline, and finally concluded that "the material is of exceptionally high quality, the best graphite in the world" Ian Walters.

RS Mines is currently working on numerous graphene related projects including;

  • The integration of it's natural, high carbon, highly crystalline, vein graphite products into the manufacture of multi layer graphene via a green, wet chemical method, which is being developing and scaled up, in-house.
  • Manufactured graphene/multi layer graphene to be targeted to disrupt the following industries;
    • Disrupting the energy storage industry, by providing the solution to safer, longer lasting energy storage cells, with minimal charging times.
    • Replacing of Platinum and Titanium in Dye Sensitised Solar Cells.
    • Graphene thin films for water purification for drinking purposes.
    • Graphene polymer and carbon fiber enhancements, providing the next level of strength and weight reduction.
    • Conductive inks / Graphene based inks for printed electronic applications.
    • Conductive polymers.
    • Graphene for drug delivery.
    • Graphene sensors.
    • Printed graphene for the use in flexible transparent screens.
    • Graphene Oxide - the solution for the neutralisation of radionuclides (in association with AZ Electronics/Merck).

Just goes to show you how truly amazing this material really is. if any of these areas are of your expertise contact us to collaborate.

It is clear to see how Graphene is allowing us to move products and technology to the next thresholds, allowing for greater weight reductions but adding to overall strength. Our Technical Director, Dr. Vyom Parashar described the integration of graphene as re-inventing the bicycle wheel, and that is exactly what it will do. It will have the same wave effect as what Bakelite had to industries in the early 1900s.

There are some exciting applications which graphene will enhance, especially in the electronics industry, moving industry standards well into the Terahertz, and with graphene being the key base to various doped material enhancements, the new materials utilising graphene will no doubt push the limits even further.

Various routes to graphene have emerged ranging from all kind of different material sources and process, however one key aspect is certain, the graphene you produce is directly related to the starting carbon source used.

Since 2010, there has been a tremendous surge in the number of universities and companies racing to secure their patents of manufacturing graphene, there have been well over 50,000 patents applied for in the field of graphene, but will they matter?

One noteworthy method of obtaining high quality graphene is via the lasering of graphene oxide.

Take a look at the video below in which Rice University combine laser technology to produce a Super Capacitor on a Graphene Oxide Film.
