Projects > SWNT Deposition

The development of new methods for the processing of single-walled carbon nanotubes (SWNT) soot is critical to the use of these nanometer sized wires for a wide variety of new materials.  We have developed a new method for separating high aspect ratio SWNTs from the many impurities that result from their growth without greatly increasing their defect density.¹ 









 Unbundled SWNTs are unbundled, purified and then deposited using a method developed in this research group (left).  Before and after atomic force microscopy images (center and right, respectively) of deposits formed using this method demonstrate the important role that purification plays in forming a high quality 2-dimensional network of SWNTs.
