Abstract
A system for producing a layer of aligned carbon nanotubes, the system comprising: a sprayer, a solution delivery tube configured to deliver a carbon nanotube solution to the sprayer, the carbon nanotube solution including carbon nanotubes dispersed in chloroform, and a reservoir configured to contain a water subphase. The sprayer is configured to generate a continuous spray of the carbon nanotube solution. The continuous floating layer is supported by the subphase. The spray of carbon nanotube solution includes droplets of the carbon nanotube solution, the droplets having a median diameter in a range from about 1 to about 100 microns. The sprayer maintains the continuous floating layer of carbon nanotube solution on the subphase as a substrate is inserted into or removed from the subphase, the carbon nanotube solution being in contact with the substrate.
