Abstract This study aimed to elucidate the role of bio-inspired texture geometry in wettability and ice adhesion. Micro/nano pillars with different geometric parameters were first designed and fabricated, and ice adhesions on textured surfaces were then measured using an apparatus developed in-house. The surface with hierarchical micro-nano-pillars herein had the least ice adhesion, which was far less than the surface with micro-pillars and smooth surface without any structure (MN
