  • Patent number: 10395804
    Abstract: Embodiments in accordance with the present disclosure include methods, polymers, and complexes. For example, a method embodiments includes providing a solution including a disassembled supramolecular polymer and a bond disrupting agent, adding an antisolvent to the solution to precipitate the supramolecular polymer, and isolating the precipitated supramolecular polymer from the bond disrupting agent. The isolated supramolecular polymer is configured to selectively disperse single-walled carbon nanotubes (SWNTs) of a particular electrical type from a SWNT mixture including SWNTS of at least two electrical types.
