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.
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
The latest crop of coating and sealant materials and devices has impressive credentials. Many are designed for tough environments with broad operating temperature ranges, and they often cure faster, require fewer process steps, and produce less waste.
A new program has been proposed for testing and certify 3D printing filaments for emissions safety. To engineers who've used 3D printers at home this is a no-brainer. It's from a consumer on Kickstarter, and targets use in homes and schools.
For the last 50 years, the Metal Powder Industries Federation (MPIF) has sponsored an awards competition for creative solutions to designing and fabricating near-net-shape parts using powder metal (PM) technologies. Here are the seven Grand Prize winners of the 2015 contest.
Graphene 3D Lab has added graphene to 3DP PLA filament to strengthen the material and add conductivity to prints made with it. The material can be used to 3D print conductive traces embedded in 3D-printed parts for electronics, as well as capacitive touch sensors.
