Abstract:
Superior anti-icing and active deicing multifunctional surfaces are highly desired in outdoor infrastructure and work of aircraft, automobiles, wind turbines, power transmission, etc. Herein, inspired by microstructures and functions of natural opal and Nepenthes pitcher plants, we present a novel multifunctional inverse opal slippery anti-icing surface (IOSAS) by employing a combined method of colloidal nanoparticles self-assembly, microstructure mold replication, and hydrophobic lubricating fluid infiltration. Because of the 3D long range ordered nanoscale porous structure of artificial inverse opal, the lubricating liquid could wick into, wet, and stably adhere to IOSAS, forming thousands of solid-liquid interfaces and defect-free and inert slippery surface. Thus, the IOSAS was imparted with inhibiting ice nucleation property and hindering heat transfer and ice crystals’ growth characteristics.
