PU composite film provides protection for wind turbines in extreme conditions
Zhengzhou, China – Wind turbines located at high altitude can sometimes have reduced power generation efficiency because of ice building up on the blades. They can also suffer from solid particle erosion. Now, scientists at Zhengzhou University’s National Engineering Research Centre for advance polymer processing technology have developed a PU-based film that may help.
The film is a flexible thermoplastic composite that contains carbon nanotubes/graphene nanoplatelets, and was created via a spray hot pressing method. As it has a low filler content at 2% by weight, it can be heated up to 96.5°C at 9V, giving rapid electrothermal deicing. It also has excellent solid particle erosion resistance, they said.
