Researchers develop a polyurethane composite film to protect wind turbine blades

Wind turbines located at high altitudes sometimes experience reduced power generation efficiency due to ice forming on the blades. They may also be subject to erosion by solid particles. Now, scientists at the National Engineering Research Center for Advanced Polymer Processing Technology at Zhengzhou University have developed a polyurethane film that may help. The film is a flexible thermoplastic composite containing carbon nanotubes/graphene nanosheets produced by…
