A simple approach for the synthesis of a truly neutral aqueous solution of shortened carbon nanotubes (CNTs) is presented. Upon evaporation of the solvent, the shortened CNTs self‐assemble into belt‐like macroscopic structures of approximately 3 cm in length. After the annealing process, the macroscopic assembly exhibits a good electrical conductivity of approximately 140 S cm −1 . The possible self‐assembly process is also discussed.
