Wetting behaviors of water on nano-/micro-structured surfaces
The wetting behavior of water on nano-/micro-structured surfaces has important implications in diverse fields;such as chemistry;chemical engineering;physics;biology;and energy.Therefore;understanding the microscopic images and transition mechanisms of water on micro-nanostructured surfaces is of crucial importance.Here;focusing on the wetting behavior of water on nano-/micro-structured surfaces and based on our recent molecular dynamics simulation results;we examined the fundamental theories and research progress in wetting on nano-/micro-structured surface.The wetting dynamics on the single-scale structures and dual-scale hierarchical structures;and the"topological wetting"behavior on surfaces with closed-loop topology;were emphasized.Hence;we provided an overview of the microscopic wetting images and state transition mechanisms on nanostructured surfaces.At last;challenges and opportunities in this field were discussed.
