Title TRANSPARENT ELECTROCONDUCTIVE THIN FILM AND PROCESS FOR PRODUCING THE TRANSPARENT ELECTROCONDUCTIVE THIN FILM
Abstract

This invention provides a transparent electroconductive thin film of a single-layer carbon nanotube, which can further improve electroconductivity and light transmittance and can simplify a thin film formation process, and a process for producing the transparent electroconductive thin film of a single-layer carbon nanotube.

The production process is characterized by comprising the step of dispersing a single-layer carbon nanotube comprising a mixture of metallic single-layer carbon nanotubes (m-SWNTs) with semiconductor single-layer carbon nanotubes (s-SWNTs) in an amine solution containing an amine having a boiling point of 20 to 400[deg.]C as a dispersant, the step of centrifuging or filtering the dispersion liquid to concentrate m-SWNTs to give a dispersion liquid having a high m-SWNTs content, and the step of coating the dispersion liquid having a high m-SWNTs content onto a base material to form a thin film.
