Surface modifications are keys for a great number of applications. In order to perfectly control the surface properties, it is important to control the modification pathways. Two general pathways can be described in order to introduce modification on surfaces: the post-strategies and the ante-strategies. In this work, we focus on the comparison between the Huisgen and the Staudinger-Vilarrasa reaction for both post-surface and ante-surface modifications. Here, we focused on the possibility to use both two reactions to obtain superhydrophobic and oleophobic properties. This work includes monomer synthesis, surface modifications with alkyl, aryl or perfluoroalkyl chain.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
