▎ 摘　　要

NOVELTY - Making a graphene film, comprises: (a) obtaining a first compound that is a liquid alicyclic or liquid aromatic-hydrocarbon; and (b) irradiating the first compound with ultraviolet light (106) under conditions to yield a graphene film. USE - The method is useful for making a graphene film, which is planar or non-planar (all claimed). The graphene film is useful in the manufacture of semiconductors, transistors and energy-dense batteries. DESCRIPTION OF DRAWING(S) - The figure shows a schematic diagram of manufacturing the pure graphene film. Obtaining a first compound that is a liquid alicyclic or liquid aromatic-hydrocarbon (102) Placing the first compound in an inert atmosphere (104) Irradiating the first compound with ultraviolet light (106)
