微纳结构表面与水的浸润行为在化学、化工、物理、生物和能源等领域具有关键意义,因此理解水在微纳结构表面上的浸润微观图像和转变机制至关重要.本文主要围绕微纳结构表面水的浸润行为,基于我们近期的分子动力学模拟结果,综述了微纳结构表面浸润的基本理论和研究进展,重点介绍单一尺度结构、双尺度分层级结构表面上的微观浸润图像和动力学,以及一类具有闭环拓扑纳米结构表面上的"拓扑浸润"行为,对纳米结构表面微观浸润图像和浸润态转变机制进行概述,最后对该领域进行了展望.
Abstract
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.
