What is graphene?

Graphene, the 2010 Nobel Prize in Physics nanomaterial, is the strongest and lightest known.


It is an atomic shell of pure, two-dimensional carbon just one atom thick, perfectly distributed in a hexagonal honeycomb formation.


Graphene is superlative in numerous properties:

• Conducts electricity better than copper;
• It is two hundred times stronger than steel, but six times lighter;
• It is better than any metal to conduct heat;
• It is almost perfectly transparent, since it only absorbs 2% of light;
• Has an incredible surface area of more than 2,500 m2 per gram;
• It is flexible;
• It is impermeable to gases, including hydrogen and helium;
• It is biocompatible;
• It is waterproof;
• Chemical components can be added to its surface to alter its properties.


  • Graphene oxide

  • Graphene oxide (GO) is an oxidized form of graphene synthesized through the oxidation and exfoliation of graphite. GO shares the same structure as graphene, but includes interspersed oxygen-containing functional groups;

  • The properties and applications of graphene oxide depend on the degree of oxidation;

  • Unlike graphene, it is hydrophilic (it disperses easily in water and other organic solvents to form stable aqueous colloids);

  • Like graphene, it has a large surface area.
    It is suitable to be used in composites, since it can be easily mixed with polymers and other materials. It can be deposited on almost any substrate;

  •   It is an electrical insulator (it lacks the conductivity of graphene);
    • It is fluorescent;
    • Can be reduced to obtain lower cost / high volume graphene.
