This innovative type of self-healing coating prevents the substrate material from corroding, thereby significantly extending its service life. The modification of self-healing coatings with one-dimensional structured fillers relies on functional additives to efficiently heal coating damage, distinguishing it from traditional approaches involving microcapsules and nanoencapsulated particles. The incorporation of advanced fillers not only enhances the local reconstruction efficiency and mechanical properties of the coating but also enables the coating to heal the damage repeatedly. In this paper, the latest research progress on one-dimensional structured fillers for self-healing coatings is reviewed from three aspects: types of functional fillers with one-dimensional structures, packaging processes for repairing agents in fillers, and self-healing mechanisms of the composite coating. Furthermore, future work has been proposed to address present problems in the research of one-dimensional structured filler-modified self-healing coatings.
