Abstract:
1. An article comprising: a hydrophobic polymer surface with a water contact angle of at least about 150°; and a plurality of metal oxide nanoparticles disposed on the hydrophobic surface, at least some of the metal oxide nanoparticles being partially embedded in the hydrophobic polymer surface and partially exposed on the hydrophobic polymer surface, wherein the hydrophobic polymer surface is comprised of multi-level hierarchical structures formed from agglomerates of the metal oxide nanoparticles, at least some of the metal oxide nanoparticles partially being embedded into polymer filaments that emanate from the hydrophobic polymer surface, where the multi-level hierarchical structures range in size from 20 nanometers to 100 microns.
