Comment on Laser-generated surface structures create extremely water-repellent metals

Comments

I would love to learn more about the structure of the patterns etched into the metals. I took a quick look through the links from the article, but didn't find anything with meat. Does anyone have a link?

I'd love to see it under a microscope, or see a visualization of the pattern. Is the strategy to maximize the surface area of an existing hydrophobic material?

Link to the paper [1] (with microscopy images) in the Journal of Applied Physics leads the 3rd paragraph of the article.

Fantastic, thank you
