Abstract
A method for creating a superhydrophobic coated nanoporous assembly includes the steps of: providing a nanoporous assembly formed of discrete and/or continuous structures that provide a morphology defining pores of less than 1 micron between neighboring discrete and continuous structures; bringing gaseous plasma precursors in the presence of the nanoporous assembly and in the presence of a plasma generator; employing the plasma generator to convert the gaseous plasma precursors to the plasma state; and permitting the plasma precursors to deposit as a coating on the nanoporous assembly through plasma polymerization techniques the deposition thereof preserving the porous structure of the nanoporous assembly, the deposited coating exhibiting a surface energy of less than 30 dynes/cm.
