Fabrication of a Superhydrophobic Surface from the Amplified Exponential Growth of a Multilayer

Hierarchical micro‐ and nanostructures can be produced simultaneously by the novel layer‐by‐layer assembly described here. The multilayer films, grown by an exponential growth mechanism that can be amplified by adding silver ions, showed extreme hydrophobicity and a lotus‐leaf‐like amplification of the surface roughness. The figure clearly demonstrates the superhydrophobic nature of the multilayer film.
