Ice accretion hampers the performance of, and poses safety threats to, infrastructure both on the ground and in the air. Previously, superhydrophobic surfaces demonstrated potential as a passive means to mitigate ice accumulation. However, further studies on material solutions that can repel droplets that freeze during surface contact are urgently needed. In this video, we show the collaborative effect of substrate flexibility and surface micro/nanotexture on enhancing icephobicity to supercooled water.
