1. The problem statement, all variables and given/known data I want to know why Graphene has the properties it has, I am really struggling to find out why graphene has the properties it does. Strength, I know graphene contains covalent bonds which are strong and that it has a hexagonal lattice structure. Electrical conductance I know that each carbon atom has one free valence electron as it is covalently bonded to only three other carbon atoms and that graphene has no band gap and a high current density and a high intrinsic mobility. Flexibility, I know the carbon atoms can rotate around their bonds and that is it ! So please could someone expand on all the points made and make even more I have googled, read many many articles and have emailed the graphene institution in Manchester with little success. Any help would be appreciated, thanks in advance !
