Bottlebrush polymers have been widely studied because of their unique molecular structures and broad application scenarios. The synthesis of bottlebrush polymers by covalent bonds grafting is time-consuming

difficult to synthesize and difficult to function. By non-covalent bonding

the side chains are easily attached to the mainchain

which provides favorable conditions for the construction of supramolecular bottlebrush copolymers. The introduction of supramolecular interactions not only brings flexibility in the preparation of bottlebrush polymer

but also makes materials more responsive

reversible and other functions. This paper introduces the construction and assembly of bottlebrush polymers mediated by supramolecular interactions such as hydrogen bond interactions

host-guest interaction

metal coordination and electrostatic interactions

their respective characteristics and construction strategies are analyzed and discussed

the huge application potential and important research significance of bottlebrush polymers mediated by supramolecular interactions are expounded. Finally

the current problems and future development are analyzed and prospected.
