Ab intio static and dynamic calculations show that successive syn-additions of F-2 to the double bonds of graphene resulted in the rehyrbrization of fluorinated carbons. This in combination with steric repulsions between F atoms led to a distortion of the local geometry and severe buckling of the graphene. The weakened C-C bonds can then be broken by pyrolysis. This results demonstrate that fluorination can be a promising chemical route for cutting of graphene into smaller fragments under controlled experimental conditions.
