Abstract:
1. An article comprising: a surface, wherein the surface comprises at least one region; and a hydrophobic composite coating disposed over the at least one region, the hydrophobic composite coating being positioned on the surface so as to be exposed to an environment, wherein the hydrophobic composite coating comprises a plurality of non-aligned carbon nanotubes dispersed in a fluoropolymer, the hydrophobic composite coating comprising a sufficient amount of carbon nanotubes to have a water contact angle of least 140°, the hydrophobic composite coating comprising a carbon nanotube loading ranging from about 50% to about 95% by weight of the total solid weight of the hydrophobic composite coating, wherein the hydrophobic composite coating is a porous fabric comprising pores with pore sizes ranging from 0.1 μm to about 5 μm, an intermediate layer disposed between the one region and the hydrophobic composite coating, wherein the intermediate layer is porous with an average pore size of less than 0.1 μm, wherein the fluoropolymer is selected from a group consisting of polytetrafluoroethylene (PTFE) and perfluoroalkoxy polymer resin (PFA).
