The emerging field of biomimetics allows one to take inspiration from nature and mimic it in order to create various products, devices and structures. There are a large number of objects, including bacteria, plants, land and aquatic animals and seashells, with properties of commercial interest. The subject of interest for this research is the water fern Salvinia molesta because of its ability to trap air. Air-retaining surfaces are of technological interest due to their ability to reduce drag when used for fluid transport, ship coatings and other submersible industrial products in which drag is a concern. The purpose of this research is to mimic the air trapping ability of S. molesta in order to prove that a structure can be created in the lab that can mimic the behavior of the fern as well as demonstrate microfabrication techniques that can be utilized in industry to produce such materials. In this work, a novel methodology for the fabrication of microstructures that mimic the water-pinning and air-trapping ability of S. molesta is introduced. Water contact angle, water roll angle and adhesive force of the new microstructure and water fern are investigated.
仿生学是一个新兴领域，它可以从自然界中获取灵感，并进行模仿，从而创造出各种产品、设备和结构。有许多具有商业价值的物体，包括细菌、植物、陆地和水生动物以及贝壳等，都具有这种特性。本研究的对象是满江红，因为它具有捕获空气的能力。由于在用于流体输送、船舶涂层和其他潜水工业产品中可以减少阻力，因此具有保持空气的表面具有技术意义，在这些产品中阻力是一个关注点。本研究的目的是模仿满江红捕获空气的能力，以证明可以在实验室中创建一个结构，该结构可以模拟蕨类植物的行为，并展示可以在工业中用于生产此类材料的微制造技术。在这项工作中，提出了一种新的制造方法，用于制造模仿满江红的水钉附和空气捕获能力的微结构。研究了新结构和水蕨的水接触角、水滚角和粘附力。
