The invention belongs to the field of preparation of materials such as condensation water collection and microelectronics, and relates to a bionic water catching reinforced surface structure for inducing near-wall cluster condensation and a preparation method. According to the method, the effect of a huge number of cilia structures distributed on the surfaces of geranium leaves in moisture capture is imitated, the characteristic that rich clusters are distributed near the surface of a solid-phase medium in the near-equilibrium condensation process is utilized, and a near-wall space structure is introduced into design and construction of a strengthened surface; and the specific wall separation height of the near-wall space structure is designed according to the cluster evolution theory. According to the bionic surface, the capture efficiency of water vapor in moisture is remarkably improved, the designed and prepared reinforced structure has stable mechanical strength, the structural size has high controllability in preparation, and the bionic surface can be widely applied to water vapor capture or environment dehumidification in high-humidity occasions. Different from other condensation process enhanced surface design mainly focused on wetting characteristic modification of a surface substrate, the method is focused on induction of cluster condensation to design a near-wall space structure.
本发明属于冷凝集水和微电子等材料制备领域,一种诱导近壁团簇凝结的仿生捕水强化表面结构及制备方法。该方法仿照天竺葵叶片表面上分布着数目巨大的纤毛结构在湿气水捕获中的效应,利用近平衡凝结过程中固相介质表面附近富集团簇分布的特点,在强化表面的设计构建中引入近壁空间的结构,并根据团簇演化理论设计了近壁空间结构的特定离壁高度。该仿生表面显著提高了湿气中的水汽捕获效率,并且所设计和制备的强化结构具有稳定的机械强度,结构尺寸在制备上具有高可控性,可以广泛应用于高湿度场合的水汽捕获或环境除湿。与其它凝结过程强化表面设计主要聚焦于表面基底的润湿特性改性不同,本发明聚焦于诱导团簇凝聚而设计了近壁空间结构。
