1. A method of preparing a carbon nanotube monolayer film, the method comprising:
applying a bifunctional hydrogen-bond linker onto a substrate to prepare a surface-treated substrate;
mixing carbon nanotubes having a heteroatom-containing aromatic polymer coating film with a hydrophobic solvent to obtain a composition and contacting the surface-treated substrate with the composition; and
heat-treating the surface-treated substrate contacting the composition,
wherein the bifunctional hydrogen-bond linker has a solubility parameter of about 35 MPa1/2 to about 50 MPa1/2 and has a surface energy of about 35 mN/m to about 55 mN/m.
