A new approach to stabilize carbon nanotubes (CNTs) in aqueous solution with a reduction‐responsive water‐soluble polymer is reported. The novel polymer synthesized by a controlled radical polymerization is functionalized with pendant pyrene groups capable of adhering to the surface of CNTs through π–π noncovalent interactions, and labeled with disulfide linkages to exhibit reduction‐responsive cleavage. Upon the cleavage of junction disulfide linkages in a reducing environment, water‐soluble polymers are shed, retaining clean CNT surfaces for electrochemical catalytic reactions.
