Abstract

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.
