Title:
PRODUCTION METHOD FOR SEMICONDUCTING SINGLE-WALLED CARBON NANOTUBE DISPERSION
Document Type and Number:
WIPO Patent Application WO/2022/220239
Kind Code:
A1
Abstract:
In one embodiment, the present disclosure relates to a production method for a semiconducting single-walled carbon nanotube dispersion including a step for retrieving, after centrifuging a SWCNT dispersion to be separated that includes SWCNTs including semiconducting SWCNTs and metallic SWCNTs, an aqueous medium, and a polymer, a supernatant liquid including the semiconducting SWCNTs. The polymer is a copolymer including a constituent unit A derived from a monomer represented by formula (1), and a constituent unit B derived from a monomer represented by formula (3). (1): CH2=CR0-COOM (3): CH2=CR5-COO-(EO)p-(PO)q-R6
