N2 - In this work, surfaces with different contact angles in range of superhydrophilicity to superhydrophobicity but same morphology at the micro and submicron levels were obtained. It is achieved by nanosecond laser treatment of silicon and the subsequent hydrophobization by the layer-by-layer deposition of a PTFE coating. The resulting surfaces allow us to experimentally confirm the modeling results of important work of Du 2022 in Chem. Eng. Sci. In particular, we managed to reproduce the described effect of the contact angle transcendence suggesting a greater value of the receding contact angles than advancing for some types of surfaces.
