wheels 543 Posted November 15, 2011 Share Posted November 15, 2011 Harvard has developed a new material they call SLIPS. It is one of the most slippery materials ever created apparently. It never gets dirty, because nothing can stick to it. SLIPS (Slippery Liquid Infused Porous Surface) was inspired by carnivorous pitcher plants, whose slippery, cylindrical leaves slide insects into the digestive juices at the base of the plant. The surface of the leaves' spongelike texture is infused with water, which repels the sticky oils on insects' feet. The material is "omniphobic," repelling both water and oil-based materials. Liquids from oil and water to blood all roll right off the material when it's tilted at merely 2 degrees, compared to 5 to 30 degrees for other surfaces. The lubricating liquid in SLIPS seeps into any holes in the Teflon, so the material is also self-repairing. And because liquid does not compress at high pressure, the material works at the pressures found seven kilometers underwater. Link to post Share on other sites

Guest Posted November 15, 2011 Share Posted November 15, 2011 And because liquid does not compress at high pressure, the material works at the pressures found seven kilometers underwater. So we can safely assume the next Aussie AC challenge boat should have that on it then Link to post Share on other sites

DrWatson 381 Posted November 15, 2011 Share Posted November 15, 2011 Wow, that's pretty cool. I just looked it up a bit more. Thanks, Wheels. The paper explaining this in super geek format is in Nature. T Wong et al., Nature 477, 443–447 (22 September 2011) Bioinspired self-repairing slippery surfaces with pressure-stable omniphobicity. I'm not sure if everyone can access that paper, but if you can't and want to read about it in the aforementioned geek format PM me and I'll send it on as .pdf. http://www.nature.com/nature/journal/v477/n7365/full/nature10447.html My question: Does the lubricating fluid leak out eventually? If so that porous surface would be awesome for things to live in... Link to post Share on other sites
wheels 543 Posted November 15, 2011 Author Share Posted November 15, 2011 Here's a brain teaser for ya's all. So if a surface is totally hydrophobic, does it actually float in water omniphobicity. Is that the Capital City where all the Omniphobes live? Wow, So many big words for so early in the morning Dr W. My head hurts now. Link to post Share on other sites

wheels 543 Posted November 15, 2011 Author Share Posted November 15, 2011 Just remember though, we are not talking about something just being hydrophobic here, but so slippery, nothingcan stick to it. Link to post Share on other sites
Absolution 7 Posted November 15, 2011 Share Posted November 15, 2011 Well shoot me for thread drift then Wheels. I like the idea of something being super-hydrophobic. Lots of places where that could be useful too. Link to post Share on other sites
Matty 0 Posted November 15, 2011 Share Posted November 15, 2011 Well shoot me for thread drift then Wheels. I like the idea of something being super-hydrophobic. Lots of places where that could be useful too. That stuff looks awesome!! wonder if it available in NZ? Link to post Share on other sites
Guest Posted November 15, 2011 Share Posted November 15, 2011 So if it does not stick to anything. How will it stuck the the hull? Link to post Share on other sites
Guest Posted November 15, 2011 Share Posted November 15, 2011 So if it does not stick to anything. How will it stuck the the hull? Just wait for a oil spill in the gulf and go for a sail. upon return apply the new anti foul Link to post Share on other sites
wheels 543 Posted November 16, 2011 Author Share Posted November 16, 2011 So if it does not stick to anything. How will it stuck the the hull? It comes with a sticky side to it. You just have to be careful to paint the correct side on out of the Tin. Link to post Share on other sites
Guest Posted November 16, 2011 Share Posted November 16, 2011 Nah if its the incorrect one its for the other side of the boat!! Link to post Share on other sites
wheels 543 Posted November 16, 2011 Author Share Posted November 16, 2011 Oh I see, both sides are in the one can. Clever. Link to post Share on other sites
Absolution 7 Posted June 26, 2013 Share Posted June 26, 2013 Oh I see, both sides are in the one can. Clever. Looks like they figured that bit out... its a 2 part process and now commercially available.

idlerboat 116 Posted June 27, 2013 Share Posted June 27, 2013 Sounds amazing, but anytime I hear engeneered "nano" I get worried. If it is a true nano particle then it has the ability to penertrate most living cell walls. I have no faith nano partical development at the moment is (or can) take into consideration "unexpected outcomes". Not at all being a ludite, a good solution to the massive problem of antifouling is needed. Link to post Share on other sites
