Another approach to attack the holy grail of self cleaning surfaces: Damaged surface segments on self cleaning materials form a point of 'dirt crystalization'.

Another approach to attack the holy grail of self cleaning surfaces: Damaged surface segments on self cleaning materials form a point of 'dirt crystalization'. From these points, dirt starts to cover the surface.
This problem is addressed by Rühe's* paper [1] with a creative "shedding concept". Upon damage, water can access the water soluble glue material upon which the water repelling elements are sitting. The damaged hydrophobic element rinsed away, exposing a fresh hydrophobic element. Unfortunately, the regenerative potential is limited to the number of sacrificial hydrophobic elements.

- jaggederest 9y agoThat's literally the paper the article summarizes
- logicallee 9y agoto be fair, the article refers to the paper obliquely with the words, "just described in Langmuir by Jürgen Rühe of the University of Freiburg, in Germany." It's not a link and I couldn't find a link in the article - so it's easy to miss. why don't articles like this ever link to their primary sources? online, it just takes a hyperlink - it could be added without any additional comment, just turning a part of the sentence into a link.
- tenken 9y agoI'm not convinced anything you wrote ... is actually English! :P Because very little of it makes sense :)
- abritinthebay 9y agoYou're getting downvoted but... what doesn't make sense to you? There wasn't a lot in that comment that was super dense. Was it just some of the terms used?
