Abstract

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° and sliding angles close to 0°. Although the solid fraction was very low (0.02%), this surface could support a drop of water under a pressure of 234 Pa.
