Super-Slippery Coating Inspired by Carnivorous Plant
9/25/2013

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)

Interesting stuff

NO RATINGS
This is quite an interesting development, Ann, and the way scientists used their inspiration to create such a unique and useful material is fascinating. I wouldn't have even known about this plant, yet alone thought to use it to inspire a self-healing, durable material like this that could have a major impact on future product and device design. I am endlessly suprised by where researchers glean their creative inspiration for some of the inventions we cover.

Some carbon composite processes are moving into volume auto manufacturing, while intensive R&D is being conducted on many fronts to fast-track material and process development.
How can automakers, aerospace contractors, and other OEMs get new metal alloys that are stronger, harder, and can survive ever higher temperatures? One way is to redesign their crystalline structures at the nanoscale and microscale.
According to freelance website Upwork, demand has risen sharply since last year for engineers with experience of all kinds in 3D printing and AM.
Although a lot of the excitement about 3D printing and additive manufacturing surrounds its ability to make end-products and functional prototypes, some often ignored applications are the big improvements that can come by using it for tooling, jigs, and fixtures.
A fun and informative tour you can attend at the upcoming Design & Manufacturing Minneapolis, MD&M Minneapolis, and other events there, is the Materials Innovation Tour on Wednesday afternoon. I'll be leading it.
