Graphene-based surface offers long-term scalable frost prevention

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.
