TITANIUM DIOXIDE DISPERSION LIQUID, METHOD FOR MANUFACTURING TITANIUM DIOXIDE DISPERSION LIQUID, AND ORGANIC OPTICAL ELEMENT

摘要

A titanium dioxide dispersion liquid in which the transmittance is 80% or more is manufactured by dispersing titanium dioxide fine particles having an average primary particle diameter of 1 nm or more and 30 nm or lower in a solution containing diglyme which is a solvent and trimethoxypropylsilane which is a dispersant. By doping titanium dioxide fine particles with nitrogen atoms, and then dispersing the same by an atomization device using beads having an average particle diameter of 15 μm or more and 30 μm or lower, a titanium dioxide dispersion liquid capable of maintaining transparency stability over a long period of time is manufactured.
