Here, the combination of both the Staudinger reductive amination and amidification to prepare highly hydrophobic surfaces is reported for the first time. This approach has been studied for surface ante and post‐deposition modification. In the ante‐deposition approach, the combination of both the reactions allows to develop a one‐pot new monomer bearing two different side chains (heterobifunctional surface). The developed monomer has been successfully polymerized and leads to hydrophobic surface (θ > 110°). Similar modifications performed as post‐treatment lead to highly hydrophobic feature (θ > 120°). The difference between the ante and post‐deposition modification is investigated for their roughness and morphologies. The results of this work allow explaining this difference on surface feature and show quality and drawback of both ante and post‐deposition strategies.
