The invention relates to a preparation method of a super-hydrophobic antifouling anti-drag cilia array surface. The preparation method comprises the following steps: processing an ordered micropore array on a polydimethylsiloxane flexible substrate by adopting an ultraviolet laser marking machine, casting a mixed magnetic solution of a PDMS prepolymer and carbonyl iron powder on the ordered micropore array, growing magnetic microcilia under the action of static and dynamic magnetic fields and micropores, and then immersing the surface into a mixed solution of modified nano SiO2 particles and absolute ethyl alcohol to obtain the magnetic microcilia. And drying to obtain the super-hydrophobic magnetic microcilia array. The preparation method has the advantages of being environmentally friendly, simple in preparation process and low in cost, the surface micro-nano structure enables the array to reach a stable Cassie state, an air layer can be formed in water, the super-hydrophobic effect is achieved, the cilia structure of the array can reduce adhesion sites of algae, mussels and other fouling organisms in the ocean, and the service life of the array is prolonged. The air layer and the array cilium-shaped structure cooperate to realize the antifouling and resistance-reducing functions in the navigation process of the navigation body, so that the energy consumption is reduced, and the economic loss is reduced.
本发明涉及一种超疏水防污减阻纤毛阵列表面的制备方法。采用紫外激光打标机在聚二甲基硅氧烷柔性基底上加工有序的微孔阵列,将PDMS预聚物和羰基铁粉的混合磁性溶液浇铸在其上,在静、动态磁场和微孔作用下生长磁性微纤毛,后将表面浸入改性纳米SiO2颗粒和无水乙醇的混合溶液中,烘干后得到超疏水磁性微纤毛阵列。该制备方法兼具环保、制备工艺简单和低成本的优点,表面微纳米结构使该阵列达到稳定Cassie状态,在水中可形成空气层,达到超疏水效果,阵列纤毛状结构在海洋中可以减少藻类和贻贝等污损生物的黏附位点,空气层和阵列纤毛状结构协同作用,实现航行体航行过程中的防污减阻功能,进而节约能耗和减少经济损失。
