Unwanted frost accumulation is a major concern across industrial, residential, and government sectors,” said Northwestern’s Kyoo-Chul Kenneth Park, who led the study. “For example, the 2021 power crisis in Texas cost $195 billion in damages, resulting directly from frost, ice, and extreme cold conditions for more than 160 hours. Thus, it is critical to develop anti-frosting techniques, which are robust for long periods of time in extreme environmental conditions. It is also necessary to develop anti-frosting methods which are easy to fabricate and implement. We designed our hybrid anti-frosting technique with all of these needs in mind. It can prevent frosting for potentially weeks at a time and is scalable, durable, and easily fabricated through 3D printing.”
