"Superomniphobic" Nanoscale Coating Repels Almost Any Liquid
cylonlover writes "A team of engineering researchers at the University of Michigan has developed a nanoscale coating that causes almost all liquids to bounce off surfaces treated with it. Creating a surface structure that is least 95 percent air, the new 'superomniphobic' coating is claimed to repel the broadest range of liquids of any material in its class, opening up the possibility of super stain-resistant clothing, drag-reducing waterproof paints for ship hulls, breathable garments that provide protection from harmful chemicals, and touchscreens resistant to fingerprint smudges."

Heck, if we all wear slippery clothing, I guess we don't need the slip and slide anymore. We can just run and jump and hit the ground sliding off into the sunset.
Oh! What about shoe soles? To heck with rolerblades. We can just scoot around on the soles of our shoes!
Oh my God I'm having an idea-anurism!!
You can turn your clothes into a computer

It's been tried on 'postage stamp' bits of cloth. No mention of stability, durability, flammability or other useful properties.
'Superomniphobic', eh? Sounds like something out of a tacky Disney movie.
Faster! Faster! Faster would be better!
Obi-Wan Kenobi foretold this in 1951 http://www.imdb.com/title/tt0044876/
I repel most liquids too, although beer and coffee keep slipping though my formidable defences.
I know that lawn mowers, should you leave gas in them for a while, will gain a 'coating' that gums up the fuel needle in the carburetor. Cleaning out the carb is a true pain and costs a lot to get a mechanic to clean/replace. Would this kind of coating over that small and delicate part help ease/eliminate sticking?
Every x months for the past 5 years I hear about some new super-coating that repels dirt, water, oil etc.. Every time I'm like, "cool, when will it come standard on new cars?" I hate having to wash my car every few days (it's parked outside) or it starts looking like crap.
I suppose when I get a flying car, that's when I'll finally see this miracle coating in action.
I know a few Democrats that were superromneyphobic.
and comes right back out for reuse
We're 60 percent water. Maybe it will repel us.
now we need to go OSS in diesel cars
I wonder how it compares with that 'NeverWet' or Rain X stuff. Apparently, the contact angle of the former for a drop of water is around 160-175 degrees (close to perfect 180), but may have problems with durability (and is pervious to solvents, detergents, soap and high pressure water). The latter - Rain X - is already in commercial use, namely for car windscreens, but only has a contact angle of 110 degrees, so isn't superhydrophobic.
I refer to my earlier post which gave these stats:

So a shirt that you essentially can't wash? You get charcoal or some other dust and you're out of luck!
No more changing wipers!
Read: "super laundry-resistant clothing." Once you do get something on the clothing, water-soluble detergents won't be able to attack it.
This "Superomniphobic" Nanoscale Coating Repels Almost Any Liquid, but on the other hand, MIT's also nanoscale Liquiglide non-stick coating allows even sticky stuffs such as ketchup to flow out of the bottle completely.

I must admit that I'm not familiar with both of these technological development, so... Can someone familiar with them explain to us the similarity / compatibility of both developments?
Thanks !
Muchas Gracias, Señor Edward Snowden !
Ketchup -> Born slippy.
Science advances one funeral at a time- Max Planck
Sorry, been programming all day and it's the first thing that came to mind.
For extra smooth slip n' slide? Don't want it on the inside, the thing will slip right off. Or maybe just put the coating on the outside and also just the inside tip.
excellent news! now i can wear my blue dress all month long!
Will it repel all bodily fluids?
I can coat myself in this and win every swimming competition by running along the bottom of the pool?
A bunch of engineering researchers at the University of Michigan have new matching white suits.
It's my understanding that this kind of surface erodes relatively quickly, and thus rapidly loses its liquid repelling properties as it is handled or touched by other things that are solid in far too brief a time to be practical for anything but a temporary coating.

John Gotti is now "The Superomniphobic Don".
Wouldn't coatings with complex surface geometry like that have issues with friction wearing them flat? I could see that not being a big deal on rigid surfaces that don't really contact anything, but other products, like clothing seem like they would be especially troublesome. Even on things like windshields seem like they would pose a problem with the wiper blades constantly rubbing the surface down.
Quoting one spokeswiccan, "I'll get you, my pretty, and your little dog, too!"
Have gnu, will travel.
phobicity? ...philicity?
weren't phobia and ...philia good enough already?
It seems if it were a paint it might help. Once. The second coat could be problematic.
Finally, I get the obvious juvenile post first!
I hope this can be used to improve athletic clothing that's supposed to whisk away sweat. Nothing I work out in seems to "work".
A superominphobic coating when placed horizontally should cause drops of liquids to levitate. Gravity wins however. This coating is very high omniphobic. Super? Not so much.
And the sucker will just come out quietly.
There were four companies at CES showing coated cellphones that could be put underwater without harm.
(for a limited time)
Saw something about this (or related to at least) recently on BBC:
http://www.dailyflix.net/index.php?/topic/51005-richard-hammond%E2%80%99s-miracles-of-nature-2012/
It's based off of a moth's wings. They wondered how it managed to fly in rain and discovered it had a criss cross ridges at the nanoscale that reduced the area available to water droplets. It's a similar principle to lying on a bed of nails.
If it were a flat surface the droplet would burst and coat the area, but as it doesn't it remains a drop and just rolls off.
That's all from memory and I don't know for sure if it's the same tech but you can watceh the show for yourself ;-)
and subsequently banned in controversial Olympic swimsuits
wears off from flexing. Right now you can repel HCL and H2SO4 with NanoTex stain resistant clothing. My last lab coat I needed or the lab was treated with this product already from the manufacturer. Because All acids are mostly water, so repel the water instead. IF you are spilling concentrated acid on yourself, you need to be kicked in the nuts for being a danger in the lab.
Do not look at laser with remaining good eye.
do i really need to explain "tire tracks" ???
we'll have hyperomniphopic, then turbo-omniphopic, then überomniphopic, etc. and all the while we'll still see few, if any, real world applications. These nanoscale surfaces are just too fragile. They'd probably work well for disposable products (although that raises the issue of how well garbage breaks down when it can't even get wet). For some of the most useful applications, the coating would have to be re-applied regularly. That raises the issue of safety of such products. I can only imagine what kind of havoc this stuff would wreak if you were do breath an aerosolized version. Plain liquid versions would be manageable, but even then you'd probably have to wear impervious gloves to make sure it doesn't just soak right in to your bloodstream and head straight for your dura mater. It's fascinating to think of all the possible applications, yet scary as shit to think of all the side effects.
You mean Republican?
Easy. One is for INSIDE the diaper, the other for OUTSIDE.
I've never been able to figure out how a coating can "repel" a neutrally-charged molecule (like water, say). Seems like the best you can do is just be as non-polar as possible so that you don't cause any static polar or induced Van Der Waal's attractions, such that the liquid is attracted to *itself* much more than to your coating.
