When the host molecules become aligned, they cause the carbon nanotube fibers to also become aligned in the same direction. The film of aligned carbon nanotubes is then cured into a permanent phase, which can then be polished to produce a thin film of commonly aligned carbon nanotube fibers for use within a field emission device.Other References
