Many outdoor devices require effective snow prevention solutions, yet existing passive anti-icing technologies are inadequate for repellency due to the variability of properties. This study addresses this gap by proposing a bioinspired micro-grooved anti-snow structure that minimizes van der Waals forces through reduced contact area and mitigates capillary effects via V-shaped design, facilitating separation liquid water at interface. Snow-shedding performance is shown be highly sensitive surface roughness, with periodic smoothness micro-grooves significantly reducing mechanical interlocking snow. In contrast, hierarchical superhydrophobic structures strongly interlock ice grains, preventing spontaneous snow-shedding even extremely low adhesion forces. By embedding nanoparticles into micro-groove structure, presents multifunctional design integrates anti-icing, anti-snow, water-repellent Experimental results demonstrate effectively balances reduction performance, showing promising potential photovoltaic solar power systems large-scale architectural applications.
