In this work we describe self-assembled surfaces with a peculiar multiscale Moncler Schweiz Kaufen organization, from the nano to the microscale, exhibiting the Cassie-Baxter wetting regime with extremely low water adhesion: floating drops regime with roll-off angles < 5. These surfaces comprise bundles of hierarchical, quasi-1D TiO2 nanostructures functionalized with a fluorinated molecule (PFNA). While the hierarchical nanostructures are the result of a gas-phase self assembly process, their bundles are the result of the capillary forces acting between them when the PFNA solvent evaporates. Nanometric features are found to influence the hydrophobic behavior of the surface, which is enhanced by the micrometric structures up to the achievement of the superhydrophobic Cassie-Baxter state (CA>>150). Thanks to their high total and diffuse transmittance and their self-cleaning properties these surfaces could be interesting for several applications such as smart windows and photovoltaics where light management and surface cleanliness play a crucial role. Moreover the multiscale analysis Moncler Jacken Schweiz Outlet performed in this work contributes to the understanding of the basic mechanisms behind extreme wetting behaviors.
