Title:
WATER-REPELLENT STRUCTURE AND COMPOSITION FOR FORMING WATER-REPELLENT LAYER
Document Type and Number:
WIPO Patent Application WO/2024/024461
Kind Code:
A1
Abstract:
The present invention provides a water-repellent structure including a non-fluorinated water-repellent layer which, in an initial state, has satisfactory water repellency and which has such wear resistance that, even when the surface thereof is repeatedly rubbed, the water repellency decreases little. The water-repellent structure (1) comprises a base (10) and a water-repellent film (20) formed on a surface of the base (10), wherein the water-repellent film (20) includes a water-repellent layer (21) which contains siloxane bonds and one or more kinds of organic groups bonded to Si atoms and contains no fluorine atoms, the water-repellent layer (21) having a surface (21S) which is the uppermost surface (20S) of the water-repellent film (20). The surface (21S) of the water-repellent layer (21) has a modulus distribution and has, in an arbitrarily selected 1-μm square micron area, a high-modulus portion having a modulus of 6.0 GPa or greater and a low-modulus portion having a modulus of 4.0 GPa or less, the surface moduli of the micron area having a root-mean-square slope of 3.5 GPa or greater.
