Title:
導電性基材上への金属酸化物微粒子層の形成方法
Document Type and Number:
Japanese Patent JP4842025
Kind Code:
B2
Abstract:
There is provided 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 extremely easily as compared with conventional plating method, CVD method, liquid coating method, electrodeposition method or the like. The method for forming a metal oxide fine particle layer on a conductive substrate 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. The dispersion further contains colloidal particles having a mean particle diameter of 2 to 300 nm.
