Meet the "Wonder Material" that could revolutionize the world. Graphene. Its the Mother of all Graphitic material.One single atom thick Graphene is the world's strongest, thinnest and most conductive known to exist.
One of the very first patents pertaining to the production of graphene was filed in October, 2002 entitled, "Nano-scaled Graphene Plates“.
Two years later, in 2004 Andre Geim and Kostya Novoselov at University of Manchester extracted single-atom-thick crystallites from bulk graphite.Geim and Novoselov received several awards for their pioneering research on graphene, notably the 2010 Nobel Prize in Physics.

Graphene Structure

  • Graphene is a 2-dimensional network of carbon atoms. 
  • These carbon atoms are bound within the plane by strong bonds into a honeycomb array comprised of six-membered rings. 
  • By stacking of these layers on top of each other, the well known 3-dimensional graphite crystal is formed. 
  • It is a basic building block for graphitic materials of all other dimensionalities. 
  • It can be wrapped up into 0D fullerenes, rolled into 1D nanotubes or stacked into 3D graphite.
  • Thus, graphen is nothing else than a single graphite layer. 

Graphene Properties

  • Graphene is chemically the most reactive form of carbon.
  • graphene has a high carrier mobility, as well as low noise
  • It is a zero-overlap semimetal (with both holes and electrons as charge carriers) with very high electrical conductivity.
  • High charge carrier mobility, for which values of 10,000 cm2/Vs, in some cases even 200,000 cm2/Vs were reported. 
  • Graphene, despite it is only 1 atom thick, is still visible to the naked eye.
  • Due to its unique electronic properties, it absorbs a high 2.3% of light that passes through it.

Graphene Applications

  • Bio medical- reading the sequence of chemical bases in a DNA strand 
  • Integrated circuits- High Performance Processor,Terahertz-speed transistor
  • Optical Electronics-touchscreens, liquid crystal displays, organic photovoltaic cells, and OLED
  • Filters-Desalination,Ethanol distillation
  • Energy Storage Devices: Supercapacitors
