摘要
Polymer fibers are an important class of materials throughout human history,evolving from natural fibers such as cotton and silk to modern synthetic fibers such as nylon and polyester.With the advancement of materials science,the development of new fibers is also advancing.Polymer fibers based on dynamic covalent chemistry have attracted widespread attention due to their unique reversibility and responsiveness.Dynamic covalent chemistry has shown great potential in improving the spinnability of materials,achieving green preparation of fibers,and introducing self-healing,recyclability,and intelligent response properties into fibers.In this review,we divide these fiber materials based on dynamic covalent chemistry into monocomponent fibers,composite fibers,and fiber membranes.The preparation methods,structural characteristics,functional properties,and application performance of these fibers are summarized.The application potential and challenges of fibers based on dynamic covalent chemistry are discussed,and their future development trends are prospected.
