International Excellence Talks

International Excellence Grants and FellowshipsJulia Schade

Excellence lives on exchange and networking among the best researchers worldwide. That is why we want to invite you to join us in a new lecture series, International Excellence Talks, where internationally renowned scientists will give insights into their current research topics and, ideally, inspire a broad audience of scholars. This monthly event will include a 30-minute keynote lecture and a platform for networking and informal exchange among researchers with a wide range of interests. Recordings of previous talks can be found at KIT International Excellence Talks YouTube Channel.

Abstract: The nature-inspired wettabilities that either extremely repelled or allowed effortless sliding of different liquids (oil/water) in air or underwater are with immense potential for various prospective applications. In common practice, essential chemistry and appropriate topography that conferred the special liquid wettabilities were mostly and generally achieved by associating delicate chemistry. Eventually, the synthesized materials suffered from poor durability issues. In the literature, very few designs are capable of providing durable bio-inspired wettability—but fabrication processes remain generally complex. Moreover, the integration of various other relevant physical properties with such durable liquid wettability is highly challenging to achieve.
Hence, design of robust bio-inspired liquid wettability following a simple fabrication process that would allow to integrate different and relevant physical properties is utmost important for various fundamental and applied contexts. Related to this, recently, our research group has extended conjugate addition reactions between amine and acrylates at ambient conditions to develop tolerant and functional liquid wettability. The controlled tailoring of different bioinspired liquid wettability from the porous and che-mically reactive interfaces—following strategic post modulation of the chemically reactive inter-faces will be discussed in this invited lecture. A strategic association of adequate crosslinkers can provide a highly tolerant and hard superhydrophobic coating on geometrically complex and soft materials. Such a simple chemical approach also allowed to reveal important fundamental aspects related to different bio-inspired wettability. Taking advantage of the durable bio-inspired wettability, the synthesized nature inspired interfaces were successfully applied to demonstrate some practically relevant applications—including controlled release of small molecules, water splitting, oil/water separation, water harvesting, sensing, anticounterfeiting etc.
