WebDec 14, 2024 · A surface is considered to be hydrophilic if its static CA is below 90°, and superhydrophilic if this CA is lower than 10°. By contrast, surfaces with a static CA higher than 90° are hydrophobic, and if the CA is higher than 150°, the surface can be considered as superhydrophobic [ 5 ]. Superhydrophilicity refers to the phenomenon of excess hydrophilicity, or attraction to water; in superhydrophilic materials, the contact angle of water is equal to zero degrees. This effect was discovered in 1995 by the Research Institute of Toto Ltd. for titanium dioxide irradiated by sunlight. Under light irradiation, water dropped onto titanium dioxide forms no contact angle (almost 0 degrees).
