Herein, self-assembled superhydrophobic composite coatings were successfully prepared using a one-step dip-coating method on different irregular parts. The fluorinated nano-SiO₂ particles spread into a uniform layer owing to the viscosity of the composite resin. After the optimization of the process, the fabricated nanoporous-structured coating has low adhesion properties with chemical and high thermal stabilities. After baking at 250 °C for 2 h or soaking in a solution of pH = 1 or pH = 13 for 10 days, the coating could maintain its good superhydrophobicity. The self-ejecting effects of the condensed dewdrops and droplet bounce phenomenon indicate that the coatings can be well-distributed on components of different structures, and they have significant application prospects in irregular parts and industrial production in the near future.

本文采用一步浸涂法在不同的不规则部位成功制备了自组装的超疏水复合涂料。氟化纳米SiO ₂由于复合树脂的粘度，颗粒分散成均匀的层。经过优化工艺后，制成的纳米多孔结构涂层具有低附着力，化学稳定性和高热稳定性。在250°C下烘烤2小时或在pH = 1或pH = 13的溶液中浸泡10天后，涂层可以保持其良好的超疏水性。凝结的露珠和液滴反弹现象的自喷射效应表明，该涂料可以很好地分布在不同结构的部件上，并且在不久的将来将在不规则零件和工业生产中具有重要的应用前景。
