MAGS is a universally applicable icephobic surface that takes advantage of magnetic fluid and liquid-liquid interactions to dramatically reduce the median nucleation temperature of ice and increase the freezing delay time of water. MAGS consists of a magnetic field, a substrate, and oil-based ferrofluid, making it easily manufactured. It has been shown that the substrate material has no effect on performance, therefore, making MAGS universally applicable. With increasing magnetic field, the median nucleation temperature is decreased and the average freezing delay is increased. Due to the hydrophobic characteristic of the oil-based ferrofluid, the slightest force or any degree of surface tilt will remove ice that has formed on the surface. MAGS offers a robust and durable approach to icephobicity that can be applicable in various operations and infrastructures including transportation and roofing.
