对水粘附的控制对于例如水收集、液体输送和水/油分离中的许多应用是极其必要的。受玫瑰花瓣和壁虎脚等自然物种的启发，这些特性可以通过表面结构的地形来控制。在这里，我们报告的第一次电沉积粘附导电聚合物形成纳米丝或纳米片上纹理网状基板。我们表明，存在的网格纹理可以减少水的粘附力，虽然粘附力仍然保持相对较高。这可能是由于网丝之间的空气量高，而网丝上的空气量低。此外，还可以通过网孔或通过改变纳米结构的形状来控制水的粘附。这项工作开辟了新的策略，控制水的粘附。
Control over water adhesion is extremely necessary for many applications in water harvesting, liquid transportation, and water/oil separation, for example. Inspired by natural species such as rose petals and gecko feet, these properties can be controlled with the topography of surface structures. Here, we report for the first time the electrodeposition of sticking conducting polymers forming nanofilaments or nanosheets on textured mesh substrates. We show that the presence of mesh textures can reduce the water adhesion, although the adhesion still remains relatively high. This is probably due to a high amount of air between the mesh wires and a low amount of air on them. Moreover, it is also possible to control the water adhesion with the mesh opening or by modifying the shape of the nanostructures. This work opens new strategies for the control of water adhesion.
