Manufacturing method of Titanium dioxide nanoparticles dispersed solution Titanium dioxide nanoparticles dispersed solution manufactured by the same and preparing method of Titanium dioxide film using the Titanium dioxide nanoparticles dispersed solution having excellent deodorization effect for removing formaldehyde ammonia acetaldehyde acetic acid and toluene

摘要

The present invention relates to a method for manufacturing a titanium dioxide nanoparticle dispersed solution, the titanium dioxide nanoparticle dispersed solution manufactured by the same, and a method for manufacturing a titanium dioxide thin film using the same, wherein the method for manufacturing a titanium dioxide nanoparticle dispersed solution comprises: a step of preparing a hydrochloric acid aqueous solution which is stirring 34 to 36 mass% of the hydrochloric acid aqueous solution; a mixed solution forming step of dropwise mixing a titanium tetra-alkoxide precursor in the hydrochloric acid aqueous solution; a first aging step of the mixed solution; and a second aging step of the mixed solution after the first aging is completed. Through this invention a particle size of the titanium dioxide nanoparticle can be minimized without addition of a separate additive, and since titanium dioxide nanoparticles do not aggregate with each other, it has a high level of contribution to environmental aspect, thereby being able to be widely used in various fields.
