The patterning of surfaces with sub-micrometer scale is a key factor for many applications in physics and biology. The nano-imprint lithography has emerged as a promising technique to replicate nanostructures. This technique is essentially based on the deformation and solidification of the surface of a film which is in contact with a stamp.

In the laboratory, we have developed a one-step, fast and potential low cost process to make silica like glass nanostructures by combining sol-gel chemistry and thermal nanoimprint (see Nanostructuration by sol-gel embossing).

We search to extend this technique to microstructures. The main objective is to control and to characterize the super-hydrophobic behavior of these textured surfaces.
