WebThe sigma bonding system acting within a single graphene layer is exceedingly strong. In fact, it is probably the strongest 2 dimensional network structure known, and is the structural backbone of all carbon/graphite fibers, and carbon nano-tubes. The strength of the sigma bond in carbon is also illustrated by the high hardness of diamond.
