“…The morphology of the cells was observed by a fluorescence microscopy (CX41-72C02, Olympus) after the cells were stained by calcein AM/PI. The relative cell viability was calculated by the following equation (Li et al 2016 ; Zhao et al 2020 ): where A Hydrogel and A Control are the absorbance for cells cultured in the hydrogel piece and in cell culture medium, respectively. For each hydrogel formulation, three independent cultures were prepared and cytotoxicity test was repeated three times.…”

“…Reversible crosslinks are found in dynamic covalent bonding (Zhang et al 2018), hydrogen bonding (Zhao et al 2020), ionic bonding (Wang et al 2020b), supramolecular (Mohamadhoseini and Mohamadnia 2020), and hydrophobic interactions (Wang et al 2019b). The degree of selfhealing ability depends upon the number of linkages and strength of moieties.…”

Polymer materials are vulnerable to damages, failures, and degradations, making them economically unreliable. Self-healing polymers, on the other hand, are multifunctional materials with superior properties of autonomic recovery from physical damages. These materials are suitable for biomedical and tissue engineering in terms of cost and durability. Schiff base linkages-based polymer materials are one of the robust techniques owing to their simple self-healing mechanism. These are dynamic reversible covalent bonds, easy to fabricate at mild conditions, and can self-reintegrate after network disruption at physiological conditions making them distinguished. Here we review self-healing polymer materials based on Schiff base bonds. We discuss the Schiff base bond formation between polymeric networks, which explains the self-healing phenomenon. These bonds have induced 100% recovery in optimal cases.

When it comes to underwater adhesion, mussel is the true expert that can firmly attach onto wet rocks under dynamic and turbulent environments. Catechol‐like 3,4‐dihydroxyphenylalanine and its biochemical interactions have been largely implicated in mussels' strong adhesion to various substrates. We successfully determined that a copolymerization polymer molecule could be designed according to the catechol structural features and that high‐performance biomimetic mussel materials can be prepared from petrochemical materials or renewable materials, and because of their excellent performance in various application areas show a broad application prospect. The adhesion mechanism of the mussel protein and the recent advances in biomimetic mussel protein polymers based on nonphytogenic catechol derivatives and phytogenic catechol derivatives from different sources are comprehensively summarized. By comparing the application of nonphytogenic catechol derivatives and phytogenic catechol derivatives in industrial and biomedical fields, we found that the synthesis of phytogenic catechol derivatives is more facile and universal, and their application performance is as good as that of nonphytogenic catechol derivatives. In addition, the challenges and prospects for this field in the future are also discussed. © 2021 Society of Industrial Chemistry.
