Special Issue Information

Dear Colleagues,

Self-healing materials based on smart polymers represent a rapidly advancing frontier in materials science, offering the ability to autonomously repair damage and extend the lifespan of structural and functional systems. This Special Issue, ‘Innovative Polymer-Associated Self-Healing Materials: From Design to Applications’, highlights recent breakthroughs in the molecular design, synthesis, and application of polymeric materials capable of mimicking biological healing processes. Contributions explore diverse mechanisms such as reversible covalent bonds, supramolecular interactions, microcapsule-based healing, and vascular networks integrated within polymer matrices. Emphasis is placed on stimuli-responsive behavior—triggered by heat, light, moisture, or mechanical stress—that enables on-demand repair in coatings, composites, electronics, and biomedical devices. The Issue also addresses challenges in characterizing healing efficiency, scalability, and long-term performance under real-world conditions. By bridging fundamental chemistry with practical engineering needs, this collection showcases how functional, self-healing, smart polymers are paving the way for sustainable, durable, and adaptive technologies across aerospace, healthcare, soft robotics, and infrastructure sectors.

This review provides an overview of the latest advances in bionic vascular self-healing cement, focusing on vascular design, fabrication, selection of healing agents, transport and curing mechanisms, and performance evaluation methods. Compared to systems based on microcapsules and microorganisms, vascular networks enable directed and efficient transport of healing agents and repeated healing; however, the presence of hollow channels results in an inevitable loss of mechanical properties. Additive manufacturing, in situ printing based on Pickering emulsions, and direct printing of cement-based or multi-material systems have enhanced geometric flexibility and scalability. However, issues such as channel quality, polymer-cement interface stability, and on-site quality control remain unclear. Regarding the selection of healing agents, epoxy resin systems are generally more suitable for structural healing, polyurethanes are suitable for rapid sealing and wide or irregular cracks, while silicate healing agents are suitable for healing where cement compatibility and durability are prioritized. The most critical research gap lies in the lack of standardized, full-scale, multi-cycle, and long-term environmental validation, which limits the practical engineering application of vascular self-healing technology. Future research should prioritize the integrated design of various performance metrics, the long-term durability of polymers, standardized benchmark testing, and validation based on actual service conditions.
