Abstract: In this work, we demonstrated that arc discharge carbon nanotubes produced by our lab could be acted as the channel materials after sorted by polymers. It was found that PFO-BT, PFⅡD, PCZ and PCZⅡD showed the ability to selectively separate sc-SWCNTs from pristine arc discharge carbon nanotubes produced by our lab. Among them, PCZ and PCZⅡD with the higher molecular weight and larger conjugated units showed higher efficiency to separate sc-SWCNTs. As-prepared sc-SWCNT inks could be used to directly construct thin film transistors by inkjet printer, and printed SWCNT TFTs showed good electrical properties with on/off ratio of 8×105 and effective mobility of 6.8 cm2·V-1·s-1.

Key words: inkjet printing, semiconducting carbon nanotube, thin-film transistor
