Water-droplet adhesions of the coatings constructed by all-polymer multiscale hierarchical particles (MHPs) were finely adjusted within the range from highly adhesive to self-cleanable. The MHPs were synthesized via thermal-induced polymerization of the reactants absorbed into self-made hollow reactors and in situ capping of nanocomplexes onto the reactors' shell simultaneously. The dynamic wettability of the prepared MHPs was tuned between water-droplet sliding and water-droplet adhering by simply controlling the type of capped nanocomplexes. Water-adhesive force changed in the range from 31.28 to 89.34 μN. In addition, the raspberry-like particles (MHPs without nanocomplex capping) were used to construct superhydrophobic rose-petal-like surface with a high water-adhesive force, which can be applied in microdroplet transportation without loss. The MHPs with appropriate nanocomplex capping were used to fabricate superhydrophobic lotus-leaf-like fabric, exhibiting excellent antifouling property and superior mechanical stability. We believe that the prepared superhydrophobic MHPs with diverse water-adhesive forces are promising in potential academic research and industrial applications.
通过将反应物吸收到自制的中空反应器中并同时原位将纳米复合物包覆在反应器壳上，热引发聚合合成了多尺度分级粒子（MHPs）。通过简单控制包覆的纳米复合物的类型，调节了所制备的 MHPs 的动态润湿性，使液滴在滑动和附着之间进行切换。水粘合力在 31.28 到 89.34 μN 的范围内变化。此外，使用覆盆子状颗粒（未包覆纳米复合物的 MHPs）构建了具有高水粘合力的超疏水玫瑰花瓣状表面，可用于微液滴输送而不会损失。用适当的纳米复合物包覆的 MHPs 可用于制备超疏水荷叶状织物，表现出优异的抗污性和卓越的机械稳定性。我们相信，具有不同水粘合力的制备的超疏水 MHPs 在潜在的学术研究和工业应用中具有广阔的前景。
