Abstract
Embodiments of methods of making superhydrophobic structures comprise depositing a polymer mold onto a silicon surface comprising a plurality of microasperities, removing the polymer mold after the polymer mold has hardened, depositing a liquid epoxy resin into the polymer mold, forming a microstructure with a plurality of microasperities by separating the epoxy resin from the mold after the epoxy resin has solidified, and forming a superhydrophobic structure by depositing a plurality of alkane nanoasperities on the microstructure in the presence of solvent vapor.
