目前的研究表明，荷叶结构的超疏水行为可以通过创建一个蜂窝状的多层表面覆盖二氧化硅纳米粒子来模仿。通过用半氟化硅烷涂覆这种高度纹理化的多层表面来实现超疏水性。即使在长时间浸泡在水中后，表面仍保持其超疏水特性。讨论了从多层膜中产生稳定的超疏水涂层所需的关键结构元素。
The present study demonstrates that the superhydrophobic behavior of the lotus leaf structure can be mimicked by creating a honeycomb-like polyelectrolyte multilayer surface overcoated with silica nanoparticles. Superhydrophobicity was achieved by coating this highly textured multilayer surface with a semifluorinated silane. The surface maintains its superhydrophobic character even after extended immersion in water. The key structural elements needed to create stable, superhydrophobic coatings from polyelectrolyte multilayers are discussed.
