Methods of forming films of aligned carbon nanotubes on a substrate surface are provided. The films are deposited from carbon nanotubes that have been concentrated and confined at a two-dimensional liquid/liquid interface. The liquid/liquid interface is formed by a dispersion of organic material-coated carbon nanotubes that flows over the surface of an immiscible liquid within a flow channel. Within the interface, the carbon nanotubes self-organize via liquid crystal phenomena and globally align along the liquid flow direction. By translating the interface across the substrate, large-area, wafer-scale films of aligned carbon nanotubes can be deposited on the surface of the substrate in a continuous and scalable process.

The second temperature is higher than the first temperature.
