THIN FILM CONTAINING CARBON NANOTUBE

摘要

A thin film containing a single wall or multi-wall carbon nanotube, wherein the material for forming said film is gelatin or a cellulose derivative; a luminescent material using such a single-wall carbon nanotube; and a dispersion containing a multi-wall carbon nanotube, wherein the dispersant is a cellulose derivative. In the above thin film, single wall carbon nanotubes (SWNT) or multi-wall carbon nanotubes (MWNT) are present in a state wherein they are separated from one another and optical and electronic characteristics and functions inherent in a separated single wall carbon nanotube can be satisfactorily expressed. In the above dispersion, multi-wall carbon nanotubes are uniformly dispersed, and the dispersion is safe and reduced in the load to the environment and can be produced at a low cost.
