Abstract
Provided is a process for producing a structured surface possessing a high level of hydrophilicity, wherein the process involves: coating a surface with a mixture to produce the structured surface, wherein the mixture includes: particles (a) having a number average particle diameter of from 0.1 μm to 10 μm; and particles (b) having a number average particle diameter of from 5 nm to 0.5 μm and a 20° C. surface energy of greater than or equal to 80 mN/in, and wherein the mixture exhibits a bimodal particle diameter distribution of particles (a) and particles (b). The mixture may optionally include an aqueous liquor, an emulsifier, a binder, an adhesion promoter, a thickener, and/or a pigment. Also provided is a structured surface produced by the process. A non-limiting example of the structured surface produced by the process is a structured textile surface.
