Abstract: Methods of sorting carbon nanotubes and methods of forming films of aligned carbon nanotubes using rod-coil copolymers are provided. The rod-coil copolymers have a tri-block or di-block architecture and include a conjugated polymer segment (“rod” segment) that binds the copolymer to the carbon nanotubes via pi-pi interactions and a non-conjugated polymer segment (“coil” segment) that aids with the sorting and dispersion of the carbon nanotubes in solution and/or controls the spacing of the carbon nanotubes in films made therefrom.
