Abstract：Polymers play a key role in across numerous industries, and the evolving requirements for advanced materials necessitate superior properties, especially higher strength and toughness. One approach to achieving these goals involves the introduction of polyrotaxane crosslinkers that feature a unique slide-ring crosslinking mechanism. These rings are allowed to slide along the molecular chains strengthening mechanical properties of materials, and it offers an effective enhancement strategy for various polymer systems. In this work, we summarize diverse synthesis methods of cyclodextrin polyrotaxane and analyze their differences in the first section. The practical applications of polyrotaxane crosslinkers are introduced in the following section, including hydrogels, thermoplastic polyurethane, artificial spider silk, polymer binders, and stimulus-responsive polymer soft materials. Last but not least, we provide a succinct conclusion and prospects of latest research progress of polyrotaxane crosslinkers.
