Title:
METHOD FOR PREPARING POROUS TITANIA THIN FILM BY USING CELLULOSE NANOCRYSTAL
Document Type and Number:
WIPO Patent Application WO/2018/110720
Kind Code:
A1
Abstract:
The present invention relates to a porous titania thin film and a preparation method therefor. A composite material according to the present invention allows for a simple thin film formation process because of the use of cellulose crystals, makes it easy to control the structure of the titanium dioxide thin film provided therefor, has a large specific area, and is superior in terms of scratch resistance and photoactivity, thus finding useful applications in the various fields utilizing titanium dioxide as a photocatalyst.
