Making carbon nanotubes as usable as common plastics. By using an inexpensive, already mass produced, simple solvent called cresol, scientists have discovered a way to make disperse carbon nanotubes at unprecedentedly high concentrations without the need for additives or harsh chemical reactions to modify the nanotubes. In a surprising twist, researchers also found that as the nanotubes' concentrations increase, the material transitions from a dilute dispersion to a thick paste, then a free-standing gel and finally a kneadable dough that can be shaped and molded.
