<p>This study investigates the effect of slippery lubricant-impregnated surfaces (SLIPS) on freezing time delay and ice adhesion compared to hydrophilic, hydrophobic, and superhydrophobic surfaces. Visualization experiments were conducted in a freezing environment (−10 ∼ −30 °C) to analyze the droplet freezing process and ice adhesion through side and bottom views. According to the results, SLIPS can provide freezing delay performance compared to other surfaces due to minimal contact angle deterioration in freezing environments. While superhydrophobic surfaces showed a significant wetting transition due to moisture condensation around the droplet periphery, SLIPS maintained more consistent surface characteristics owing to its immiscibility with water and low freezing point of the lubricant layer. However, ice adhesion tests revealed that SLIPS exhibited unexpectedly high adhesion strength compared to superhydrophobic surfaces, attributed to mechanical interlocking between the frozen droplet and test sample via the lubricant layer. This study provides insights into the mechanisms of contact angle deterioration during icing processes and highlights both the advantages and limitations of SLIPS for anti-icing applications.</p>
