DailyDirt: Like Water Off A Duck's Back...

Surfaces that repel water are pretty fascinating to watch in action, especially on clothes when possible stains are magically avoided. There are plenty of other uses for hydrophobic materials that are cool, and some newer materials are omniphobic -- even superomniphobic. Here are just a few examples of these products that may be protecting all of our gadgets someday.

A superhydrophobic coating called NeverWet can make a variety of materials extremely water resistent -- preventing things like ice buildup, corrosion and biofilm formation. As a demo, coating an iPhone with this stuff allowed it to be submerged for 30 minutes and still work... [url]
Bio-inspired materials can be omniphobic -- repelling both oil and water. Plants do it. Maybe educated ~~fleas~~ humans can, too. [url]
Ceramic materials that repel water could form more durable hydrophobic coatings. Rare earth oxides aren't so rare, and they could potentially create some pretty cool superhydrophobic surfaces. [url]
A recently-created superomniphobic surface coating repels almost any liquid except chlorofluorocarbons. Non-Newtonian liquids also seem to "bounce" off this stuff -- which hasn't been seen before. [url]

Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.

Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.

While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

Whoa.
The bottommost item leads to this scary malware-site alert:

The link you requested has been identified by bitly as being potentially problematic. This could be because a bitly user has reported a problem ...

The link you requested may contain inappropriate content, or even spam or malicious code that could be downloaded to your computer without your consent, or may be a forgery or imitation of another website, designed to trick users into sharing personal or financial information.

Oddly, it looks like it's supposed to go to phys.org, a site that's generally regarded as reputable (except by the rather overly-conservative Peerguardian, which seems to think it's hostile to P2P but which is also known for producing frequent false positives).

Re: Whoa.
The link makes by browser choke for over 15 minutes before I killed it.

Possibly caused by some Ads or what. Beware.

hmmmn...
Am I the only one who thinks it's cool than something omniPHOBIC of water an oil is being used to obviate the need to use something omniPHILLIC of water and oil (soap)?

Metamaterial engineering is AWESOME.

I think that iPhone is still probably toast. Sure, you coat it with that substance and it repels water, but in order for it to keep working, you'd also have to gunk up the charging port, the phone jack, etc. with the water-repellant, which would in itself render the phone rather useless.
