由直径为20 nm的纳米颗粒组成的双层纳米结构在直径为100 nm的纳米颗粒上显示出强大且近乎完美的超疏水性，即水接触角接近180度，滑动角接近0度。虽然固体分数很低(类似于0.02%)，但在234pa的压力下，这个表面可以支撑一滴水。
A two-tier nanostructure comprising a 20-nm-diameter "nanograss" on 100-nm-diameter nanopillars exhibits robust and near-perfect superhydrophobicity, that is, water contact angles close to 180 degrees and sliding angles close to 0 degrees. Although the solid fraction was very low (similar to 0.02%), this surface could support a drop of water under a pressure of 234 Pa.
