Abstract
Metal complexes (“compatibilizers”) having properties particularly useful for treating and compatibilizing nanomaterials (i.e. carbon nanotubes, nanofibers, nanographite) include metal cations and anionic surfactants. The treated nanomaterials can be isolated as solid treated nanomaterial and used in further applications where increased dispersion is desirable.
