Disclosed are a carbon nano-tube (CNT) thin film treated with chemical having an electron withdrawing functional group and a manufacturing method thereof. Specifically, the CNT thin film comprises a CNT composition to be applied on a plastic substrate. The CNT composition comprises a CNT; and chemical connected to the CNT and having an electron withdrawing functional group. In addition, the method for manufacturing a CNT thin film comprises steps of preparing a CNT; treating the CNT with chemical having an electron withdrawing functional group; mixing the CNT treated with the chemical with a dispersing agent or dispersing solvent to prepare a CNT dispersed solution; and forming a CNT thin film with the CNT dispersed solution. According to the CNT thin film and the manufacturing method thereof, a resistance of an electrode is decreased to improve the electric conductivity of the electrode.

A compound containing at least two pyridinium derivatives in its molecular structure and being in a reduced form thereof may be used as a CNT n-doping material. The compound may donate electrons spontaneously to CNTs to n-dope the CNTs, while being oxidized into its stable state. An n-doped CNT that is doped with the CNT n-doping material may maintain a stable n-doped state for a long time without being dedoped even in the air and/or water. Further, the n-doped state may be easily controlled when using the CNT n-doping material.
