Ultrafine metal oxide particle dispersion liquid and ultrafine metal oxide particle thin film

摘要

An ultrafine metal oxide particle dispersion liquid is prepared by mixing an ultrafine titanium-based composite metal oxide particle dispersion liquid prepared by hydrolysis in a microemulsion containing a hydrophobic dispersion medium, water, and a surfactant and an organic metal compound solution for the same titanium-based composite metal oxide at a ratio of 1:1 to 1:30 in terms of the composite metal oxide contained.
