    摘要: 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°.

    摘要: A nanoporous network includes carbon nanotubes (CNTs) with the network having a pore size in a range from about 15 nm to about 35 nm. The nanoporous network can be coated, compressed, or any combination of these operations in the manufacture of various articles. A method of making a nanoporous network includes disposing a concentrated aqueous CNT solution in a mold, freezing the concentrated aqueous CNT solution, and subliming the frozen concentrated CNT solution in a vacuum chamber.
