Document Type and Number:
WIPO Patent Application WO/2023/171226
Kind Code:
A1
Abstract:
A water-repellent glass comprising a glass base having a first surface and a water-repellent film disposed on the first surface of the glass base, wherein the first surface of the glass base has a characteristic region where some of the glass base has gathered into the shape of particles, the characteristic region having particulate characteristic objects integrally extending from the glass base. When the thickness direction of the glass base is referred to as a first direction, the characteristic region has a first-direction dimension in the range of 50-2,000 nm. When a straight line LA is drawn perpendicularly to the first direction, the straight line LA has crossing portions which cross a plurality of particulate characteristic objects contained in the characteristic region. The crossing portions have an average dimension in the range of 20-5,000 nm. At least some of the particulate characteristic objects each have a constricted portion which narrows toward the inside of the glass base.
