Abstract : Ice-repellent coatings can have significant impact on the global energy saving and improving safety in many infrastructures, transportation. Recent efforts for developing ice-phobic surfaces have been mostly devoted to utilize lotus leaf-inspired superhydrophobic surfaces, yet these surfaces fail in high humidity conditions due to water condensation and frost formation and even lead to increased ice adhesion due to a large surface area. We are going to present a radically different type of ice-repellent material based on Slippery, Liquid-Infused Porous Surfaces (SLIPS), where an ultrasmooth and slippery liquid interface is maintained by infusing a water-immiscible liquid into a nanostructured surface. We develop a direct method of SLIPS on industrially relevant metals, particularly aluminum-allow, one of the most widely used materials as lightweight structural materials for aircraft, marine vessels, and construction materials. SLIPS-coated Al surfaces not only suppress ice/frost accretion by effectively removing condensed moisture even in high humidity conditions, but also exhibit at least an order of magnitude lower ice adhesion than state of the-art materials. Based on a theoretical analysis followed by extensive icing/deicing experiments, we discuss special advantages of SLIPS as ice-repellent surfaces. We show report that our surfaces remain essentially frost-free even in high humidity conditions, in which any conventional materials accumulate ice. These results indicate that SLIPS is a promising candidate for developing robust anti-icing materials for broad applications in aircraft industries ,marine industries and auto-mobile industries Key Words- Anti-frost surfaces, Nanostructure coating, slippery liquid-infused porous surface, electro-deposition.
