| Zusammenfassung: | Slippery liquid-infused porous surfaces (SLIPS) have attracted widespread attention for their excellent anti-icing properties. However, their poor durability and limited scalability have severely hindered practical industrial applications. In this study, a simple method combining laser ablation and roll-to-roll thermal embossing is proposed to fabricate a large-area armor-protected flexible SLIPS (AF-SLIPS) with outstanding mechanical durability and anti-icing performance. AF-SLIPS can be efficiently produced over a large area via roll-to-roll thermal embossing, ensuring suitability for large-scale industrial applications. Moreover, it exhibits an ultralow ice adhesion strength of 8 kPa, approximately 35 times lower than that of the original substrate (286 kPa). Besides, even under bent conditions, both water droplets and a large-area ice block (A = 30 cm2) can easily slide off the surface, demonstrating excellent anti-icing performance and flexibility. Furthermore, benefiting from the protective armor structure and the capillary action of the porous hydrophobic nanoparticle coating, silicone oil is firmly locked within the porous nanostructures of AF-SLIPS. Even after 50 cycles of sandpaper abrasion or tape peeling, AF-SLIPS maintains a low ice adhesion strength (<25 kPa), indicating superior mechanical durability |
