The planes are stable, especially in the winter. As passengers wait to board the ship, the longer the delay when the planes need to be finished with thousands of gallons of deicing water to help them fight the cold winter. But by the time the plane took off, most of the water had left the surface of the plane and ended up polluting the streams and lakes.
In an effort to create the most efficient frost products for such demanding professionals and customers, Sushant Anand, UIC assistant professor of mechanical engineering, and Rukmava Chatterjee, a UIC Ph.D. students, has developed a longer option than conventional deicers. They say it can benefit other businesses.
“We questioned the viability of cryoprotectants and looked at new ways to increase their effectiveness,” says Anand. “The glycol melts very quickly in water and washes away before the plane takes off, and the cost of hundreds of millions of dollars is a serious problem – most of which actually ends up in the air. rivers. themselves, and do other things that can last a long time to be more biofriendly. And that’s what we’ve done. “
To achieve their goal, the researchers have developed a large family of more than 80 anti-freezing coatings, which can be counted as polymeric solutions, emulsions, creams and gels. The components can be easily used in aluminum, steel, brass, glass, plastic or industrial components without preconditioning or expensive chemicals.
“Our covers are a complete package that can delay the formation of ice for long hours while at the same time melting any ice created on its skin by the gentle wind or the melting. Of the substrate, ”Chatterjee said.
Their work is described here High article entitled “A family of ice-cold and icephobic cover.”
The convertible pieces are a family of synthetic and multifunctional coatings that can be used to recycle materials, from ice to bacteria, regardless of their material properties and chemistry. . This was done by regulating the leakage of chemicals from the property system and creating a lubricating board that was slippery and free of ice.
Anti-freezing gels are also important for applications such as train signs, traffic lights to assist brakes during landing, car windshields or other vehicles. windows windows.
“Consider covering your smart watch with our gel that can prevent the build -up of harmful substances while preventing bacterial infections,” says Chatterjee.
“Because our anti-icing sprays are bio-friendly and anti-bacterial, we believe they can be used in agriculture to prevent plants from being destroyed by heavy snow,” he said. and Anand. “But that’s a pipe dream, and we need to do more research to see if there are any long -term adverse effects on plants.”
A global conservation document entitled “Compositions and Methods for Inhibiting Ice Formation on Surfaces” has been filed by UIC’s Office of Technology Management.
“There’s a lot of power in these for a lot of applications, and I think the day is near when the commercial powers of our products will come out,” Anand said.
Anand Research Group members Hassan Bararnia and Umesh Chaudhuri joined Chatterjee in the experiments.
Manufacturers can make ice last up to 300 times longer than anti-icing pads.
