Surface modifications influence material interactions such as wettability, imparting hydrophobicity or hydrophilicity. Mainstream research focused on enhancing product shelf-life, directs attention towards superhydrophobic surfaces (SHS). SHS offer several benefits for outdoor applications such as self-cleaning, anti-soiling, anti-mist etc. In this manuscript, we explore the possibility of combining structural and chemical modifications to metal substrates in order to create superhydrophobic metal oxide surfaces. ZrO2-nanotubes are evaluated with regard to their application as transparent UV-stable superhydrophobic coatings. Nanostructured oxide surfaces are created via single-step electrochemical anodization. The absence of HF acid-based pre-etching steps offer a safe and alternatively a green synthesis route. Anodized oxides are modified using octadecylphosphonic acid self-assembled monolayers, demonstrate superhydrophobicity and are evaluated for their mechanical stability under a jet of water, chemical stability under indirect sunlight irradiation in air/water and direct UV exposure. Zirconia nanotubular films were evaluated for optical transparency using light microscopy and surface wettability of the different zirconia-composites was compared to the model system-titania. Structural and compositional differences of the SAM layer upon time dependent decay were analyzed with X-ray photoelectron spectroscopy. <br>

Injection Moulding Process

The lotus effect known from nature has so far only been successfully imitated by the incorporation of additives or by modifying the polymers used. By using microstructured moulds there is now a way to produce durable, superhydrophobic surfaces in a single-step injection moulding process. This method combines shaping and functionalisation of the part in one process step. The studies show that, by selecting suitable microstructures, an increase in the contact angle by up to 40° can be achieved. At the same time, the LSR microstructures produced show good abrasion resistance.
