Researchers from Northwestern University and University of California have developed a strategy that prevents frost formation – the team reported a hybrid surface design that passively controls the diffusion of water vapor over a surface to sustain flat frost-free regions for long periods of time. The hybrid anti-frosting technique can prevent frosting for potentially weeks at a time and is scalable, durable and fabricated through 3D printing.
The team found that tweaking the texture of any surface and adding a thin layer of graphene oxide prevents 100% of frost from forming on surfaces for one week or potentially even longer. This is 1,000 times longer than current, state-of-the-art anti-frosting surfaces. As a bonus, the new scalable surface design is also resistant to cracks, scratches and contamination.
