Stable solutions of multiwalled carbon nanotubes using an azobenzene dye

We present a method to achieve stable dispersions of multiwalled carbon nanotubes (MWCNT) in tetrahydrofuran for several days. The physical chemistry of this method is based on the π-π stacking interactions between MWCNT and an azobenzene derivative, Disperse Orange 3 (DO3). Evidence of this interac...

Evidence of this interaction was obtained using UV-vis absorption spectroscopy. Our results suggest that there is a weight ratio DO3/MWCNT beyond which interactions are strong enough to achieve stable dispersions of MWCNT for at least 45 days. © 2010 American Chemical Society. 2010 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_19327447_v114_n34_p14347_Costanzo http://hdl.handle.net/20.500.12110/paper_19327447_v114_n34_p14347_Costanzo
