Antireflective Coatings with Self-Cleaning, Moisture Resistance and Antimicrobial Properties

摘要

Coated article having antireflective property together with self cleaning, moisture resistance and antimicrobial properties can be prepared with a topmost layer of titanium oxide on an antireflective layer, which can be formed by a sol-gel process. The antireflective layer can comprise a porosity forming agent, or an alkyltrialkoxysilane-based binder. The antireflective coating can comprise silica and titania components, with pores to achieve low index of refraction and titania to achieve self-cleaning and antimicrobial properties.

主权项

1. A coated article comprising:
a transparent substrate; a plurality of first coatings formed above the transparent substrate, wherein each of the plurality of first coatings comprises at least one silica component and at least one titania component, and wherein at least two of the plurality of first coatings have different formulations of silica and titania components, the formulations differing with respect to a precursor included therein; and a second coating formed above the plurality of first coatings, wherein the second coating comprises a titania component.
