Super-Slippery Coating Inspired by Carnivorous Plant
An ultraslippery coating that repels oil and water even on vertical surfaces is created with a glass honeycomb-like structure with craters (left). This is coated with a Teflon-like chemical (purple) that binds to the honeycomb cells to form a stable liquid film. The film repels droplets of both water and oily liquids (right). Because it's a liquid, it flows, which helps the coating repair itself when damaged. (Source: Nicolas Vogel, Wyss Institute)
I like to read articles where we as humans take God's technology and try to improve or use it in a new way. There are so many cool things that are out in nature right now and to advance or use them in a new way is very exciting.
I woudl think the auto or possibly trucking industry would be inerested if it reduces drag and increases mpg. The trucking idustry will go nuts for a lb or two reduction in vehicle weight because of the potential cost savings.
VERY interesting post Ann. Several years ago I had a consulting job involved with mounting solar collectors used in a small "solar farm". It involved the base structures and motorized mechanisms to move the collectors across the horizon as the sun traveled east to west. On HUGE factor we somewhat overlooked was keeping the collector plates clean. It's amazing how much efficiency is lost due to dirty glazers. The material you describe in your post would be very effective keeping clean surfaces. I'm going to send your post to the gentleman I worked with just to keep him informed as to what might be one possible solution to the problem.
At this point, the primary difference I see in the product descriptions is the Rustoleum product doesn't claim complete transparency; several reviews comment on the "milky sheen" it imparts to the coated surface.
Ratsky, this material isn't even commercialized yet so it's definitely not being sold at Home Depot. There have been several similar R&D announcements in the last year or so of such slippery surface/coating technology. I'd guess the Home Depot stuff is the result of one of those.
Is this the same stuff that Home Depot has been advertising recently, from Rustoleum? Too many similarities to be a coincidence. This ad just started running a few days ago. HD website has many reviews, largely mixed.
HP revealed more of its 3D printing plans in a recent webinar. Senior vice president of inkjet and graphics solution business Stephen Nigro spoke about how the technology works and expanded on HP's vision of open collaboration to commercialize its Multi Jet Fusion 3D printing technology for end-production, and open collaboration on new materials. He also said HP will create software to help users decide when to use Multi Jet Fusion versus conventional subtractive manufacturing.
A lightweight electric urban concept car designed by several European companies weighs only 992 lb without its battery. It would have weighed 26.7 lb more if its windows were made of glass instead of the specially coated LEXAN polycarbonate resin from SABIC Innovative Plastics.
Skylar Tibbits' team in MIT's Self-Assembly Lab is now 4D printing self-assembling shapes made of programmable carbon composites and custom wood grain. The composites are being used in a sport car airfoil, and the wood grain is beautiful.
The NanoSteel Company has produced high-hardness ferrous metal matrix composite (MMC) parts using a new nanosteel powder in a one-step 3D-printing process. Parts are 99.9% dense, crack-free, and with wear resistance comparable to M2 tool steels.
