Gradient array micro-nano structure with water collection function, application and preparation method
The invention discloses a gradient array micro-nano structure with a water collection function, application and a preparation method, and relates to the technical field of nano material preparation, and the preparation method comprises the following steps: preparing a culture dish, and dividing the culture dish into at least two areas by using a spacer; preparing a PS microsphere template in each area, wherein the diameters of PS microspheres in each area are different; removing the spacer, preparing liquid silica gel, and covering the PS microsphere template with the liquid silica gel; the method comprises the following steps: sequentially carrying out curing, film taking and ball removing operations to obtain a silica gel film with a conical gradient array, and on the basis of hydrophobic difference caused by the conical gradient array, enabling liquid drops on the surface of the silica gel film to spontaneously drive towards a gradient positive direction which is a direction in which the diameters of the arrays are arranged from small to large. The structure completely depends on the surface hydrophobicity difference caused by the conical gradient array, so that spontaneous driving of water drops is caused, and the water collecting surface has the advantages of durability and safety.
本发明公开了一种具有集水功能的梯度阵列微纳结构、应用及制备方法，涉及纳米材料制备技术领域，制备方法包括：准备一个培养皿，使用隔片将培养皿分成至少两个区域；在每个区域内制备PS微球模板，且每个区域的PS微球直径不同；撤掉隔片，制备液态硅胶并使其覆盖PS微球模板；依次进行固化、取膜、去球操作，得到具有锥状梯度阵列的硅胶薄膜，基于锥状梯度阵列造成的疏水性差异，使得位于硅胶薄膜表面的液滴向着梯度正方向自发性驱动，梯度正方向为各阵列直径由小到大排列的方向。该结构完全依靠锥状梯度阵列造成的表面疏水性差异，从而引起水滴自发性驱动，是一种具有耐用性且安全优势的集水表面。
