Not only controlling the charge carrier species by doping but also enhancing the retention ability of doped states are necessary for implementing carbon nanotubes (CNTs) into electric devices. Here, we regarded the p-doped CNTs as “complexes composed of hole-injected CNTs and adsorbed anions for charge compensation.” Comparing the retention ability of the electrical properties of p-doped CNTs and the chemical hardness of anion species, the stabilization mechanism of doped CNTs could be understood by the complex chemistry concept. Anion-exchange process was established to improve the stability of p-doped state of CNTs at high temperature.
