Abstract
In this study, we conducted a comprehensive investigation on the role of surface topography in the anti-icing process in terms of water-ice transition prevention and bond strength deterioration. The uniform microstructures were evaluated based on the unit cell definition to document the different contact ratios while maintaining the same wettability. The survey results revealed a large difference in bond strength among the same wettability samples when it is interestingly proportional to the area fraction, confirming the importance of textured structures in ice removal performance. In addition, a thermal conduction approach was proposed to qualitatively determine the phase transition time of water volume forming on the functional surface. The real-time investigation results agreed well with the theoretical calculation, emphasizing the importance of considering surface parameters and suggesting rational designs for ice-phobic surfaces.
