Carbon nanotubes (CNTs) have been integrated into many electronic and energy devices due to their high conductivity and flexibility. Here, we report the discovery of poly (p-styrene-sulfonic acid) (PSS) as an efficient dispersant and stable dopant for CNTs. PSS showed an excellent dispersion performance; CNTs were partially dispersed by just stirring and well dispersed by sonication for only 3 min in PSS aqueous solution. PSS also showed an excellent doping performance; the as-filtrated CNT films, which had CNT bundles wrapped with a few nm-thick PSS layer, showed low sheet resistances of 115 and 49 Ω/sq at optical transmittances of 90% and 79%, respectively. Moreover, the CNT films showed long-term stability (>1000 h) and high-temperature stability (250 °C) in ambient air without any passivation layer. The simple dispersion and stable doping for CNTs is a promising way to achieve superior transparent conductive films for fundamental and industrial applications.
