Articles comprising neat, aligned carbon nanotubes and methods for production thereof are disclosed. The articles and methods comprise extrusion of a super acid solution of carbon nanotubes followed by removal of the super acid solvent. The articles may be processed by wet-jet wet spinning, dry-jet wet spinning, and coagulant co-flow extrusion techniques.
