Biomimetic Superhydrophobic Surfaces by Nanoarchitectonics with Natural Sunflower Pollen (Small 7/2025)

Superhydrophobic Surfaces In article number 2409136, Nam-Joon Cho and co-workers introduce biomimetic superhydrophobic surfaces inspired by the micro- and nanostructures of natural sunflower pollen. These surfaces, fabricated using polydimethylsiloxane and silane additives, exhibit remarkable water-repellent properties. By emulating the characteristics of a ‘lotus leaf,’ they achieve high contact angles and low sliding angles, making them highly effective for applications such as water displacement in pipelines and self-cleaning surfaces.
