Water collection surface structure and preparation method thereof
The invention discloses a moisture collection surface structure and a preparation method thereof, and belongs to the technical field of moisture collection, the specific structure comprises a super-hydrophobic substrate and a super-hydrophilic surface on the super-hydrophobic substrate, the super-hydrophilic surface comprises a spindle-shaped pattern and a wedge-shaped pattern which are vertically communicated in a coplanar mode, the spindle-shaped pattern and the wedge-shaped pattern are lower than the end face of the super-hydrophobic substrate, and the moisture collection surface structure is formed through preparation of the super-hydrophobic substrate, preparation of the super-hydrophilic surface and laser ablation of the spindle-shaped pattern and the wedge-shaped pattern. According to the water collecting surface structure, the updating frequency of liquid drops in a super-hydrophobic area can be increased, collected water can be rapidly discharged under the action of surface energy gradient force and Laplacian gradient force, and therefore the water collecting efficiency is effectively improved.
本发明公开了一种水分收集表面结构及其制备方法，属于水分收集技术领域，具体结构包括超疏水基底以及在超疏水基底上的超亲水表面，超亲水表面包括竖向共面连通的纺锤形图案和楔形图案，纺锤形图案和楔形图案低于超疏水基底端面，该水分收集表面结构结构通过超疏水基底制备、超亲水表面制备和纺锤形图案和楔形图案激光烧蚀形成。本发明的水分收集表面结构能够增大超疏水区域液滴的更新频率，在表面能梯度力和拉普拉斯梯度力的作用下能将收集的水分快速排走,从而有效提高集水效率。
