Abstract
In accordance with the invention, there are articles including hydrophobic composite coating and methods of forming a hydrophobic composite coating. The method of forming a hydrophobic composite coating can include providing a substrate, wherein the substrate can include at least one region. The method can also include providing a dispersion including a plurality of carbon nanotubes, a stabilizer, a hydrophobic polymer, and a solvent, wherein the plurality of carbon nanotubes can be selected from the group consisting of single wall carbon nanotubes and multiple wall carbon nanotubes, and wherein each of the plurality of carbon nanotubes has an aspect ratio of at least about 10. The method can further include applying the dispersion to the one region to form a coated substrate and heating the coated substrate to form a hydrophobic composite coating such that the hydrophobic composite coating has a water contact angle of at least about 120°.
