NOVELTY - An ion-induced assembling graphene self-supporting material comprises graphene sheet of three-dimensional structure having pore or a cavity. USE - Ion-induced assembling graphene self-supporting material (claimed). ADVANTAGE - The ion-induced assembling graphene self-supporting material is prepared easily with variety of forms and functions, by controlling thickness and microstructure. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of ion-induced assembling graphene self-supporting material, which involves adding 1 pt. wt. graphene oxide, 20-500 pts. wt. solvent, and 0-1 pt. wt. 25% ammonia to a container, stirring to obtain graphene oxide dispersion, taking base material, adding adsorption ion crosslinking agent solution to base material, immersing base material in graphene oxide dispersion, leaving to stand for certain time, adhering base material to graphene oxide gel, freeze-drying the gel, removing the base material to obtain graphene oxide self-supporting material, and chemically reducing or thermally treating.
