The purpose of the present invention is to provide a carbon nanotube thin film in which carbon nanotubes exist in a uniformly dispersed state, the thickness and light permeability of the film can be adjusted easily and are uniform, and high electrical conductivity or high semiconductor properties can be achieved. Carbon nanotubes are mixed with an electrically-non-conductive matrix capable of dispersing the carbon nanotubes satisfactorily therein, such as hydroxypropyl cellulose, to prepare a dense ink that is dispersed in a solvent, the ink is prepared into a film having a uniform thickness employing a doctor blade method or a screen printing method, and subsequently the electrically-non-conductive matrix is removed with a solvent or by a photonic curing method or an oxygen plasma treatment. In this manner, a thin film in which the electrical conductivity or semiconductor properties inherent in carbon nanotubes are recovered can be produced. |
