Graphine is very strong here is why

 Graphine is very strong here is why

Sheet of grapheme looks like an atomic scale honey comb

It made of pure carbon stacked on top of each other 

Its most conductive substance on earth

Can be used to make long lasting batteries, faster microchip flexible circuitry implantable biosensor and more

Can convert light at any wavelength into current 

Because graphene is made of  carbon, carbon atom is covalently bonded to three other carbon at item, which give the material incredible strength

Why it conduct electricity? Each carbon atom has four electron in its outer shell but only three of these electrons are shared with neighboring three carbon atom

The  remaining electron which called pi electron is free to move
