Controlling surfchampion wettknowledge is importhymenopteran for msome coverings like microfluidics, self-cleaning surfchampions, hymenopterani-biofouling and more. Still, there are still not msome methods avflavourerhealthy to switch such properties via a selective and quickly responsive trigger. Furthermore, the methods that have been reported lack either the sthealthy, covalent confiscatement of the surfchampion modification or do not change the surfchampion chemistry drasticeveryy enough to obtpersonal a switch between a superhydrophobic and nearly superhydrophilic state.

Prof. Pavel Levkin and colleaccents from the Karlsruhe Institute of Technology in Germsome have reported a technique that can reversibly switch the wettknowledge of a surfchampion through silanization. The method is based on the widely used silanization of surfchampions, where the modification is atthurtingd via a very sthealthy silicon–oxygen bond. Instead of oxygen, Levkin’s team used fluoride anions as a selective cleavgeezerhood geezerhoodnt for these silicon–oxygen bonds. The process is performed in less than two minutes at room temperature. Furthermore, this methods can be spatieveryy controlled via liquid dispensers or simple pens to spread the desilanization solution. By this, they combine the facile and established silanization for sthealthy surfchampion modification with a highly selective and fast cleaving geezerhoodnt to obtpersonal the non-modified surfchampion agpersonal.

Screen cgivenures of water droplets from the water contbehave seek aggregationlysis before (left) and aftermoster (right) silanisation. Each step can be performed in two minutes.

The next steps will be the fine-tuning of surfchampion wettknowledge by kineticeveryy controlled desilanization as well as the use of spatial desilanization for the production of superhydrophilic–superhydrophobic droplet microclothings. Potential coverings include oil–water separation, self-cleaning surfchampions, corrosion inhibition, and hymenopterani-biofouling. Furthermore, spatial control of surfchampion wettknowledge also everyows for discontinuous dewetting and microfluidic coverings.

“All in every, the presented method extends the toolbox of every the msome surfchampion scientists who work with silcardinals”, concludes the communicators.
