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)
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.
An in-depth survey of 700 current and future users of 3D printing holds few surprises, but results emphasize some major trends already in progress. Two standouts are the big growth in end-use parts and metal additive manufacturing (AM) most respondents expect.
