摘要:

对液滴在界面上动态行为的研究是化学和材料领域的一个重要方向,许多先进的表面和界面技术,比如集水、防覆冰、防雾、微流体控制和传热等,均属于这一范畴。通过模仿自然界中具有特殊微纳米结构和特定化学组成的生物表面,设计并构筑相应具有特殊浸润性的仿生界面,对仿生界面材料的技术应用起到了良好的先导与示范作用。本文结合本课题组的研究工作,以自然界中具有特殊微纳米结构和梯度特征的生物表面为出发点,分别从仿生多微纳米梯度界面的雾滴传输聚集调控、低温憎水/防覆冰动态调控、微液滴驱动调控3个方面,综述了近年来仿生多微纳米梯度界面的液滴动态行为调控方面的代表性研究工作,并对该领域的研究现状做出了总结和展望。

Abstract:

The study of the dynamic behavior of droplet at the interface is an important direction in the field of chemistry and materials. Many advanced surface and interface technologies, such as water-harvesting, anti-icing and anti-fogging microfluid control and heat transfer, belong to this category. Bioinspired interfaces with special wettability can be designed and constructed by imitating biological surfaces with special micro/nano structure and specific chemical composition. These studies have played a good pilot and demonstration role in the technical application of biomimetic interface materials. Combined with the research works of our group, we review the representative research work on droplet dynamic behavior regulation of bioinspired multi-micro/nano gradient interface in recent years. Firstly, biological surfaces with special micro-nano structure and gradient characteristics in nature are introduced. Then, three application aspects of bionic multi-micro/nano gradient interface are introduced: the control of fog droplets transport and aggregation, low temperature hydrophobic/ice-phobic, micro droplet actuation. Finally, the research status of this field is summarized and prospected.

Key words: Bioinspired, Wettability, Micro-nano structure, Fog harvesting, Ice-phobic, Droplet manipulation
