Abstract

Cylindrical carbon nanotubes (CNTs) pretreated by UV irradiation were able to react with NH3 to give nitrogen-containing CNTs without destroying their vertically aligned morphology. This process provided incorporation of nitrogen mostly at pyridinic and pyrrolic sites and promoted disordering, which was correlated with decreased electrical conductivity of CNT yarns.
