Abstract

We developed a novel robust technique to produce high-quality dispersions of debundled SWCNTs in aqueous solutions. Direct injection of SWCNTs treated with supercritical nitrogen into the aqueous surfactant solution facilitates the dispersion process without the need of extensive ultrasonication. According to photoluminescence and absorbance measurements, the mild ultrasonic treatment of such dispersions resulted in a higher yield of individual SWCNTs, compared to pristine tubes and tubes collected after the supercritical treatment in the form of powder.
