Abstract
A method for integrally forming a graphene film (GF) of a high specific surface area (SSA) by ultrafast ultraviolet (UV) laser processing, includes: selecting a carbon precursor material, where the carbon precursor material is one selected from the group consisting of a biomass/hydrogel composite and a heavy hydrocarbon compound; adding an activator solution to an inside of the carbon precursor material to obtain a composite with an activator uniformly loaded, and spreading the composite on a flexible substrate to form a carbon precursor material layer; heating and drying the carbon precursor material layer; in-situ processing with an ultrafast UV laser to obtain an activated GF of a high SSA; and cleaning and drying the activated GF. With the method of the present disclosure, a microporous activated GF of a high SSA can be directly processed in-situ on a flexible substrate.
