“…Many kinds of reversible bonds such as ionic interactions, hydrogen bonds, metal-ligand interactions, and dynamic covalent bonds have been used to develop self-healing materials. 46,47) However, these interactions are non-specific and thus self-healing processes are not selective. Using specific molecular recognition, resultant self-healing properties should be also specific depending on the host-guest combination (Fig.…”

Smart design of polymeric materials may lead to intelligent materials exhibiting unique functional properties. Looking at nature, living systems use specific and reversible intermolecular interactions in realizing complex functions. Hence reversible bonds based on selective molecular recognition can impart artificial materials with unique functional properties. This review mainly focuses on supramolecular polymeric materials based on cyclodextrin-based host-guest interactions. Polymeric materials using molecular recognition at polymer main chain, side chain, and termini are described. Polymers carrying host and guest residues exhibit unique properties such as: 1) formation of macroscopic self-assembly of polymer gels carrying host and guest residues; 2) stimuli-responsive self-healing properties due to the reversible nature of host-guest interactions; and 3) macroscopic motion of artificial muscle cross-linked by host-guest interaction controlled by external stimuli. An overview of recent developments in this new frontier between materials science and life science is given.

“…Thus, either a tensile test or a rheological measurement was widely accepted as the characterization method to quantify the healing extent in the literature reports. Healing efficiency relying on a tensile test can be defined as the ratio of the stress of the healed and original material [52,62]. This method is more suitable for self-healing materials which are able to stand the stress of clamps [7,63,64].…”

With the development of smart materials, stimulus-responsive self-repairing materials attract more and more research attention. Although self-healing materials including concretes, rubbers, and hydrogels have been extensively investigated in the past decades, novel functionalities or properties such as shape memory, sol-gel transition, adhesion, anti-biofouling, and electronic/magnetic property have been introduced to self-repairing systems in recent years in order to broaden the scope of their applications in energy, drug delivery, tissue adhesion, cell culture, etc. In this paper, we first present an overview of the general strategies to prepare self-healing materials and the characterization methods to assess their healing performance. Then, we mainly focus on reviewing recent progress in novel self-healing materials possessing unique functionalities and their potential applications in biomedical engineering. Finally, the challenges and scope for future development are also discussed.

“…The repair methods such as patching are not practical for all kinds of situations and applications. [22] Furthermore, repairing by "macroscopic" welding is impossible for thermoset polymer materials. Therefore, preparation of networks which could be easily welded without dimensional change seems to be necessary.…”

This study reports the use of Diels-Alder (DA) chemistry to engineer a three-step strategy for making a novel hybrid epoxy-furan network (HDAN), from DGEBA resin and the fully bio-based monomer furfuryl alcohol (FA). Thus, a furfurylated epoxy resin-(FER) was synthesized via reaction of DGEBA and FA. FER was blended with poly(furfuryl alcohol) bio-resin, and in turn crosslinked with a bismaleimide to form HDAN. HDAN showed an inferior mechanical properties but superior thermostability compared to those of a control sample i.e. aminecured DGEBA. Degradability of HDAN network was investigated both by thermal and ultrasonic methods. The results proved that the ultrasonic degradation isan alternative method for the thermal retro-DA reaction. DSC and FTIR analysis confirmed the formation, disconnection and re-formation of DA cross-linkages. Excellent thermo-remending of scratched samples and practical welding of separated sample pieces were also approved by electron microscopy. In conclusion, HDAN was considered as an initiative candidate to be used in advanced applications (e. g., polymer composites…) requiring re-processability, re-mendability and weldability.
