Lotus Coating with Nano Glass

Experimental Lotus Coating with Nano Glass

The lotus effect is the superhydrophobic property found with lotus plants' leaves. The picture shows it on nasturtium. A fine structure on the surface of the object supports the property of the material.
So nano glass powder is very effective. The powder has a particle size of about 10nm. (In the picture the particles are shown with coating for the scanning electron microscope).

The powder is spread on the surface and the solvent is evaporated. The white line marks the 100nm thickness of the wet layer. The petri dish is treated the same way. Drops are rolling on the surface. A large drop acts as a loupe. Drops combine to a resonant mass. The water can also be moved electrically with a charged plastic stick. The uncoated half of the petri dish is wetted by the water. Is that a chance for no more dishwashing with nano coated dishes? :o)


Experimentelle Lotus Beschichtung mit Nano Glas

Der Lotus Effekt ist der super- wasserabstoßende Effekt, der auf Blättern der Lotuspflanze finden ist, im Bild auf Kapuzinerkresse. Eine feine Partikelstruktur auf der Oberfläche fördert die Eigenschaft.
Das macht Glaspulverr sehr wirksam. Das Pulverr hat eine Partikelgröße von 10nm. (Im Bild sind die Partikel mit der Beschichtung für des Raster-Elektronen-Mikroskop dargestellt.)

Das Pulver wird auf der Oberfläche verteilt und das Lösungsmittel verdunstet. Die weiße Linie zeigt dabei, an welcher Stelle die Dicke der feuchten Schicht noch etwa 100nm beträgt. Die Petrischalle ist in gleicher Weise beschichtet. Tropfen rollen auf ihrer Oberfläche. Ein großer Tropfen wirkt als Lupe. Tropfen vereinen sich zu einer schwingenden Masse. Das Wasser kann auch elektrisch mit einem geladenen Plastikstab bewegt werden. Die unbeschichtete Hälfte der Petrischale wird von Wasser benetzt. Wird man sich eines Tages mit nano beschichtetem Geschirr das Geschirrspülen sparen können? :o)

Hi,

I ordered the Aerosil 9200 from Evonik and I am wondering how you coated it on glass. I tried Isopropanol but the results were not as good. Is there any other solvent I should try? Some solvent that stays on the material would be better in my opinion but I am not sure what that will be. I will try gasoline next.

Thanks

@d4dextermetal The tube for mixing the powder should be clean, especially cleaned from remaining dried glass power of an earlier mixing process. The power was added slowly in a fine distribution to the gasoline. I used a test tube and a stirrer at about 600 rpm but I am not sure it was necessary I just used it as it was there.

No more dishwashing with nano-coating but you would have to chase the soup in the plate in order to eat it :)

VSAUCE!

@A1IR Definition of SOUP PLATE

: a deep plate usualy having a wide rim and used for serving soup

[A1IR]

@ToxicWaves You drink soup from a plate?

OMG its a beyblade!

i fucking love science

@dkoribag1 what is the life span of the material that makes it hydrophobic? are there any other substances that last a long time, like years?

[RedMok25]

It's the water not the dish. I see the trick.
