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 and chemical sensors. In addition, disclosed herein is use of an s-tetrazine based polymer for purification of semiconducting single-walled carbon nanotubes (sc-SWCNTs).
Claims8
A process for producing a chemical sensor that detects one or more chemicals in the ppt to ppb range, the process comprising:
- a) applying a dispersion of a sc-SWCNT/s-tetrazine based conjugated polymer composite to a substrate;
- b) applying heat and/or UV light to decompose the s-tetrazine based conjugated polymer;
- and
- c) removing the resulting decomposition products.
