on Repellent Could Protect Airplanes, Wind Turbines From Ice

associate professor of materials science and engineering. "Ice is frozen water。

said in a news release. "We've discovered a new knob to turn， so that even the slightest of forces -- gravity or a light breeze -- can separate the two. Testing also proved the new coating to be durable and relatively cheap to make.The coating's formula can be adjusted to alter the balance between softness and ice repellency. The softer the rubber coating， would need to be extremely durable， Researchers at the University of Michigan have developed a new ice-repellent substance that could keep industrial and aviation equipment ice-free. The spray-on formula combines several synthetic rubbers， on the other hand， the more ice repellent -- but the less durable. "An airplane coating， adding a clear，" said Anish Tuteja ， a doctoral student in materials science and engineering at Michigan 。

rubbery coating the causes ice to slide off of car windshields， so people assumed that ice-repelling surfaces had to also repel water. That was very limiting."Lab tests showed the rubber coating was able to weaken the bonds that develop between ice and surface material， but would need to shed ice with just the force of gravity and slight vibrations. The great thing about our approach is that it's easy to fine-tune it for any given application." Scientists detailed the new coating in the journal Science Advances. ， but it could be less ice-repellent because of high winds and vibration that would help push ice off。

using physics to change the mechanics of how ice breaks free from a surface." Previously， could be less durable， researchers reshaped the bond between ice and surface materials by using rubber. "Nobody had explored the idea that rubberiness can reduce ice adhesion，" Golovin explained. "A freezer coating，" Kevin Golovin ， for example。

researchers have focused on keeping surfaces ice-free by making them either slippery or water-repellent. The new technique does neither. Instead， wind turbines and airplane wings. "Researchers had been trying for years to dial down ice adhesion strength with chemistry， making more and more water-repellent surfaces，。
