Superhydrophobic surfaces possess enormous potential in various applications on account of their versatile functionalities. However, artificial superhydrophobic surfaces with ultralow solid/liquid adhesion often require complicated structure fabrication and surface fluorination processes. Here, we designed a superhydrophobic surface possessed of micro/nanoscale structures by employing facile and low-cost demolding and initiated chemical vapor deposition (iCVD) processes. The achieved micro/nanostructured superhydrophobic surface has a maximum static contact angle of ∼170°, a roll-off angle and contact angle hysteresis below 1°, ultralow solid/liquid adhesion for water droplets, and maintains excellent superhydrophobicity after exposure to strongly corrosive species, like strong acid/base and salt solutions, for 60 h. This reasonability-designed method of creating the superhydrophobic surface could provide valuable guidelines for the manufacture of transferable superhydrophobic surfaces and facilitate potential applications extending from optoelectronic devices to self-cleaning materials, such as solar cells, windows, and electronic displays.
具有微/纳结构的超疏水表面通过采用简便且低成本的脱模和引发化学气相沉积（iCVD）工艺来设计，这些表面具有巨大的多功能性，在各种应用中具有巨大的潜力。然而，具有超低固/液附着的人工超疏水表面通常需要复杂的结构制造和表面氟化工艺。所获得的微/纳米结构超疏水表面具有最大静态接触角约为 170°，滚动角和接触角滞后低于 1°，对水滴的固/液附着超低，并且在暴露于强腐蚀性物质（如强酸/碱和盐溶液） 60 小时后仍能保持优异的超疏水性。这种设计合理的超疏水表面的制造方法可为可转移超疏水表面的制造提供有价值的指导，并有助于将潜在应用从光电设备扩展到自清洁材料，如太阳能电池、窗户和电子显示器。
