Abstract
A process for purifying semiconducting single-walled carbon nanotubes (sc-SWCNTs) extracted with a conjugated polymer, the process comprising exchanging the conjugated polymer with an s-tetrazine based polymer in a processed sc-SWCNT dispersion that comprises the conjugated polymer associated with the sc-SWCNTs. The process can be used for production of thin film transistors. In addition, disclosed herein is use of an s-tetrazine based polymer for purification of semiconducting single-walled carbon nanotubes (sc-SWCNTs).
