Make a superhydrophobic surface at home

- In this video we show you how to make a superhydrophobic surface (a surface which is very effective at repelling water) at home using a few simple materials. We demonstrate two different methods using slightly different equipment:
Method 1 requires:
* 91 - 99% Isopropyl alcohol (rubbing alcohol) - available at many pharmacies and groceries
* A flame and heatproof surface to work on
* A small dish to hold the isopropyl alcohol
* A thick piece of glass (we use glass from glass tile sheets sold at home improvement stores)
* Long-necked lighter
* SAFETY GOGGLES!
Method 2 requires:
* Acetone (available at home improvement stores)
* A wickless burner (available online)
* A flame and heatproof surface to work on
* A thick piece of glass (we use glass from glass tile sheets sold at home improvement stores)
* Long-necked lighter
* SAFETY GOGGLES!
Do not try this using an open dish with acetone in it - it will burn out of control. Use a wickless burner like this one: www.avogadro-l...
You will be working with flames and HOT pieces of glass. Use care - young people must have adult supervisions!
This would also work with a common lighter or gas stove, it's just the carbon from the flame. But the carbon can be easily rubbed off. Is there a way to seal the cover so it becomes more durable?
Try epoxy. Get the soot on the glass then put the epoxy on top. After the epoxy drys try peeling it off the glass. I haven't tried it yet. But my hypothesis is that it will stay embedded in the epoxy.
jazz hands Update?
Nice! I must to do this for an aluminum surface 2mm thickness, do you know about some technique?
Thanks!
Any soot formed surface will be hydrophobic!
why we have used that closed container in case of acetone
the fire produced b acetone is not easy to handle. it is advisable to cover it and use a low flame
which one works better?
How did the plastic cup become superhydrophobic?
Hi,
Realise it's the build up of carbon that must gives the resistance , is there a home made solution liquid or liquids that can be used on car windscreens and body. Clear but to make water resistant
For windshields you can get special polish for it. It will make your windshield smoother and more hydrophobic.

What is the way to make last for a long time
The other organic solvents will also produce soot particles then can't we use them
But its not transparent... Can we make it transparent ???
I ask the same question, is there a way of making it transparent clear.?
If you want to make it transparan there is a spray called ultra ever dry. I dont now any other methods. You can buy it about 50 dollars
A voice would be nice
Anyone here after "cutting water in half"?
Meeee
Bold of you to think that I have a home
