High purity semiconducting single-walled carbon nanotubes (s-SWCNTs) are desired for high performance electronic devices. To selectively disperse high purity s-SWCNTs, conjugated polymer wrapping has been demonstrated as a powerful and scalable strategy for enriching s-SWCNTs due to their selective dispersion on specific chiralities of SWCNTs. However, this approach suffers from significant contaminations by excessive conjugated polymer in solution which lower the electrical performance of SWCNTs network due to low conduction compared with SWCNTs. Here, we present a simple approach using thermal energy to minimize excessive polymers in SWCNTs solution. Using the polymer minimized SWCNTs, the SWCNT thin-film transistors (TFTs) were fabricated exhibit improved field-effect mobility and decreased contact resistance compared with polymer exceeding semiconducting SWCNTs TFT. |
