Abstract
A method for forming a metal oxide fine particle layer, by which a metal oxide fine particle layer having uniformity and excellent in adhesion, abrasion resistance, strength, etc. can be formed easily compared with the conventional plating method, CVD method, liquid coating method, electrodeposition method or the like. The method comprises immersing a conductive substrate in a dispersion of metal oxide fine particles and fibrous fine particles and applying a direct-current voltage to the conductive substrate and the dispersion. The fibrous fine particles have a length (L) of 50 nm to 10 μm, a diameter (D) of 10 nm to 2 μm and an aspect ratio (L)/(D) of 5 to 1,000. The content of the fibrous fine particles in the dispersion is in the range of 0.1 to 20% by weight in terms of solids content, based on the metal oxide fine particles.
