DISPERSION LIQUID FOR FORMATION OF TRANSPARENT CONDUCTIVE THIN FILM AND SUBSTRATE EQUIPPED WITH TRANSPARENT CONDUCTIVE THIN FILM

摘要

The purpose of the present invention is to provide a dispersion liquid that makes it possible to form a transparent conductive thin film containing carbon nanofibers at room temperature without the use of a dispersant. Provided is a dispersion liquid for the formation of a transparent conductive thin film that is characterized by: comprising carbon nanofibers, single nanoparticles of silica, and a solvent; the particle size of the single nanoparticles as measured using a transmission electron microscope being 70-100 parts by mass of nanoparticles having a particle size of 4-9 nm and 0-30 parts by mass of nanoparticles having a particle size of 2 nm or less with respect to 100 parts by mass of the single nanoparticles; and the single nanoparticles that have a particle size of 2 nm or less containing amorphous silica.
