Controlled Ice Formation
Utilizing superhydrophobic surfaces for anti-icing is getting more and more attention nowadays. However, superhydrophobic surfaces lose their icephobic property when ice covers the whole surface area. In this work, we propose a way to alleviate the impact of icing on a surface by spatially controlling the ice formation at its early stage and remedying the ice issue locally and immediately on the solid surface.
