The invention belongs to the technical field of surface antifouling and resistance reduction, and particularly relates to a super-hydrophobic antifouling and resistance-reducing magnetic response cilia array surface. A magnetic microcilia array grows on a microporous array substrate, then fluoride-free super-hydrophobic treatment is performed on the magnetic microcilia array to obtain a micro-nano multilevel structure, when the array is immersed in seawater, an air layer is formed on the surface, the solid-liquid contact area is reduced, and the super-hydrophobic effect is achieved. Besides, due to the fact that the cilia have good flexibility and magnetic responsiveness, the deflection direction of the cilia array can be intelligently controlled by applying an external magnetic field, and the surface of the navigation body is made to adapt to changes of flow field structures under different working conditions. Through the technology of combining passive control and active control, fouling organisms are prevented from being attached to the surface of the navigation body, the operation friction resistance is reduced, and then the navigation speed and the voyage are improved.
本发明属于表面防污减阻技术领域,具体涉及一种超疏水防污减阻的磁响应纤毛阵列表面。通过在微孔阵列基底上生长磁性微纤毛阵列,然后对其进行无氟超疏水处理得到微纳米多级结构,该阵列浸没在海水中时,表面会形成一层空气层,减小固液接触面积且达到超疏水的效果。此外,由于纤毛具有很好的柔性和磁响应性,通过施加外部磁场,能够智能操控纤毛阵列的偏转方向,使航行体表面适应不同工况状态下流场结构的变化。通过被动和主动控制结合的技术,防止污损生物附着航行体表面、减小运行摩擦阻力,进而提高航速和航程。
