Abstract: Disclosed in the present specification are a two-dimensional MXene surface-modified with a metal-organic network, a method of preparing the same, a MXene organic ink containing the same, and uses (e.g., an electromagnetic wave shielding material). In one aspect, the two-dimensional MXene surface-modified with a metal-organic network according to the present invention can use various organic ligands by linking the surface with the organic through the metal, and can be stably dispersed in various organic solvents, especially in industrial non-polar organic solvents as well as polar organic solvents, thereby being applied to a more general-purpose technologies, and securing stability against chemical oxidation to improve long-term stability.
