ANTI-FINGERPRINT PHOTOCATALYTIC NANOSTRUCTURE FOR TRANSPARENT SURFACES

摘要

Titania-based porous nanoparticle coatings are mechanically robust, with low haze, which exhibit short time scales for decomposition of fingerprint oils under ultraviolet light. The mechanism by which a typical dactylogram is consumed combines wicking of the sebum into the nanoporous titania structure followed by photocatalytic degradation. These Ti02 nano structured surfaces are also anti-fogging, anti-bacterial, and compatible with flexible glass substrates and remain photocatalytically active in natural sunlight.
