GRAPHENE, A WONDER MATERIAL
Graphene is two dimensional atomic crystalline layer
separated from product like graphite, charcoal etc. it is
an allotrope of carbon in the structure of a plan of sp2
bonded atoms with a molecule bond length of 0.142
nanometers.
In fact Graphite consists of millions of thin graphene
layers bonded together by strong Van der Wall forces
with interplaner spaces of about 0.335 nanometer.
