title: Dual high adhesion surface for water in air and for oil underwater.
abstract: A new type of dual high surface adhesion both in an oil/water/solid system and in a water/air/solid system is reported. A walnutlike cuprous iodide (CuI) microcrystal surface, which is composed of numerous CuI nanocrystals, shows an amphiphobic, highly adhesive surface for water in air and for oil underwater. The maximum adhesive force is about 120.3 ± 1.6 μN in the air for a water droplet and about 23.8 ± 2.1 μN underwater for an oil droplet. These findings will help us to design novel high adhesive materials in two-phase or multiphase mediums.
