Patent ID: 8331026

Claim:
A process for surface structuring which comprises forming at least one array of patterns with a submillimeter scale characteristic lateral dimension on a flat surface of a product comprising a substrate bearing at least one layer resulting from a sol-gel, wherein the structuring is done hot with a hydrolyzed sol layer based on alkoxide(s) and/or halide(s) of at least one metal chosen from Si, Ti, Zr, W, Sb, Hf, Ta, V, Mg, Al, Mn, Co, Ni, Sn, Zn, and Ce having a nonreactive organic group, the structuring is carried out by contact with a structured mask and exerting pressure as needed, and the structuring is carried out in a temperature range suited for a sufficient condensation threshold ensuring the thermal hold of the structuring, with a total structuring time less than or equal to two hours.
