Title (EN) DECOMPOSABLE S-TETRAZINE BASED POLYMERS FOR SINGLE WALLED CARBON NANOTUBE APPLICATIONS
(FR) POLYMÈRES À BASE DE S-TÉTRAZINE DÉCOMPOSABLES POUR DES APPLICATIONS DE NANOTUBES DE CARBONE À PAROI UNIQUE
Abstract:
(EN) 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).
(FR) L'invention concerne un procédé de purification de nanotubes de carbone à paroi unique semi-conducteurs (sc-swCNT) extraits avec un polymère conjugué, le procédé comprenant l'échange du polymère conjugué avec un polymère à base de s-tétrazine dans une dispersion de sc-SWCNT traitée qui comprend le polymère conjugué associé aux sc-swCNT. Le procédé peut être utilisé pour la production de transistors à couches minces et de capteurs chimiques. De plus, l'invention concerne l'utilisation d'un polymère à base de s-tétrazine pour la purification de nanotubes de carbone à paroi unique semi-conducteurs (sc-swCNT).
