Three-Dimensionally Programmed Slippery Wrinkles with High Stretchability for Tunable Functionality of Icephobicity and Effective Water Harvesting

Facile synthesis of 3D structured materials with highly slippery and stretchable properties is proposed by infusing lubricant into the wrinkled structures formed on the surface of silicone elastomer in a programmable manner. Such a method allows the formation of slippery surface with the desired 3D hierarchical structures for target applications. The developed platform shows 8.2 times lower ice adhesion strengths or 1.4 times higher water collection properties than planar slippery surface. The hierarchically structured slippery material not only effectively suppresses the crack generation, but also maintains a similar degree of original property under repeated stretching cycles.
