Abstract:
The present invention relates to a process for texturing surfaces providing the latter with superhydrophobic, superoleophobic, superhydrophilic or even superoleophilic properties. This process comprises i) a step of texturing the surface (via the deposition of nanoparticles of different sizes); ii) a step of curing the surface thus textured (with a curing agent); and, optionally, iii) a step of modifying the properties of the surface with perfluorinated (and therefore hydrophobic) molecules. This process is suitable, inter alia, for treating transparent and/or heat-sensitive materials and surfaces. Specifically, none of the steps of the process use a temperature higher than 100° C. Thus, the process of the invention is particularly suitable for treating transparent surfaces composed of non-mineral materials, such as polycarbonate for example, as it will affect neither their transparency nor their optical properties.
