A procedure for solid‐phase fluorination of graphene is described that provides fluorine addition at the interfaces of graphene with solid fluorinating reagents. Graphene sheets were formed on a copper substrate (Cu−G) with a specific wave‐like microstructure. A solid fluorinating reagent, {Pt 2 F 6 −PtF 4 } solid solution, was layered on a Pt substrate (Pt−F). Thermally activated fluorination is found to be localized to the linear contacts of the Pt−F surface with the “ridges” of the Cu−G waves, leading to alternating stripes of intact and fluorinated graphene. Thus, the use of specifically profiled substrates for the graphene layer and/or the solid‐phase fluorinating reagent offers a promising approach to create fluorinated zones of the desired shape and size.
