Ionic Self-Assembly Provides Dense Arrays of Individualized, Aligned Single-Walled Carbon Nanotubes

摘要

Single-walled carbon nanotubes (SWNTs) stand among the most studied nanomaterials owing to their uncommon mechanical, optical, electrical, magnetic, and thermal properties, which make them ideal components and building blocks for a wide range of devices and materials. The development of many such SWNT-based devices and materials underscores the need for solvent-dispersed SWNTs. Modified nanotubes are thus required to circumvent the strong tendency of these nanostructures to aggregate and precipitate. As the preservation of many of the unique physical and optoelectronic properties of SWNTs necessitates undisrupted nanotube conjugation, development of versatile noncovalent solubilization and organization strategies are essential.
