Graphene

  • Graphene is one of the allotropes for carbon besides diamond and graphite.
  • Yet they have very different properties from each other
  • The 0.1 mm size of graphene makes graphene one of the important materials in the field of nanoscience and nanotechnology.
  • Graphene sheets can produce a variety of other materials including
    • graphite
    • carbon nanotubes
    • fullerene balls

 

Physical properties of graphene

  • Strong and hard
  • Transparent
  • Good conductor of heat and electricity
  • Elastic
  • Impermeable
  • Very low electrical resistance

 

Chemical properties of graphene

  • Graphene sheets burn at a lower temperature than graphite
  • The most reactive carbon allotropes
  • The chemical reaction of graphene is still being studied by researchers

 

Uses of graphene

Category Explanation
Electronics The arrangement of atoms in graphene makes it a superior conductor
Censors Graphene has a high surface area
Biomedical Sensors, tissue engineering, drug delivery systems
Polymers and composite The high mechanical strength makes graphene suitable as a polymer composite material
Membrane
  • Water filtration.
  • Separation of water from gas mixtures
Energy
  • Longer lasting, flexible and powerful battery
  • Supercapacitor
