A supramolecular polymer and its composite with carbon nanotubes, CNTs, are described. The supramolecular polymer is an ensemble of precursors that independently contain “sticky feet” for non-covalent binding to carbon nanotube surfaces and associative groups. There is at least one of the associative groups covalently bound to each of the precursor and there is at least one covalently connecting moiety connecting associative groups within a precursor or connecting an associative group to a linker to a “sticky foot” in a precursor. When the associative groups are in a dissociative state, the supramolecular polymer precursors and CNTs can be combined to form a dispersion. Upon promotion, the dissociated associative groups in the dispersion can associate to yield a CNT/supramolecular polymer composite.

charge‐transfer (CT)‐induced supramolecularhydrogel was fabricated using pyrene‐tailored pyridinium (PYP) and 2,4,7‐trinitrofluorenone (TNF) as the electron donor and acceptor, respectively. Its thermal stability and mechanical property have been modulated effectively by altering the concentration or molar ratio of PYP and TNF. Moreover, this CT hydrogel exhibited a distinct injectable self‐healing property that
