NOVELTY - The method involves selecting N carbon nanotubes with a complete structure and arrange them in an orderly manner along Y direction at a certain interval. M graphene strips are inserted with a complete structure in a staggered manner perpendicular to an arrangement direction of carbon nanotubes at a certain interval. A two-dimensional nanoporous structure system is formed that is the two-dimensional nanoporous medium material. A spacing between carbon nanotubes and graphene strips are adjusted to ensure that achieve the required permeability and stable strength. A diameter D of the carbon nanotube is 10 nm. A length of the carbon nanotube is L1 is equal to 100 nm. A distance between the carbon nanotube is d1 is equal to 10nm. USE - Method of preparing two-dimensional nanoporous medium material used in fields of sensor and permeable membrane. ADVANTAGE - The thermal stability of the structure is enhanced. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the method of preparing two-dimensional nanoporous medium material.
