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
