Robust superhydrophobicity in large-area nanostructured surfaces defined by block-copolymer self assembly

Abstract

Robust, large area, superhydrophobic surfaces with feature sizes approaching 10 nm are fabricated by block-copolymer-based thin-film patterning. We show that tuning the nanostructure shape and aspect ratio dramatically influences the surface wetting properties, with proper control crucial for achieving superhydrophobicity. © 2013 WILEY-VCH Verlag GmbH & Co.
