Green, environment friendly, and sustainable biomass-based adhesive has been considered as an optimum alternative of petroleum-derived adhesive, yet poor water resistance restricts their advancement and popularization to a large extent. Herein, a hyperbranched cross-linking cellulose-based adhesive with a synergistic effect of covalent bonds and secondary bonds (mainly include hydrogen bond and hydrophobic effect) is synthesized based on the Maillard reaction between dialdehyde cellulose (DAC) and polyamines. The active aldehyde sites on the DAC skeleton anchor the amino group to form covalent bonds consuming a large number of hydrophilic groups, the remaining aliphatic segments of polyamines criss-cross to knit a hydrophobic network and endow the adhesive the ability to resist water erosion; integrant-exposed hydrophilic groups form intermolecular hydrogen bonds preferentially after curing and clustering due to the agglomeration effect of cellulose, which reduces the opportunity of forming hydrogen bonds with water molecules. The outstanding water resistance is manifested in two aspects: (1) the dry lap shear strength of modified adhesive increased from 1.47 to 3.29 MPa, making increments of 123.8% compared with the original DAC adhesive, the re-dry strength after 3 h of immersion in water of 63 °C or boiling achieved a breakthrough from 0 to 2.27 and 2.36 MPa; (2) the modified adhesive has a higher residual rate (above 77%) and a lower moisture absorption value (less than 22.2%) compared with the neat DAC adhesive (49 and 26.6%). The work provides an underlying approach to prepare wood adhesive with excellent bonding performance and eminent water resistance based on green and cheap raw materials and simple cooking chemistry.

“…Based on this unique property of these adhesives, they got an attraction in recent years (Tang et al 2017). Knowing the importance of selfhealing-adhesives and their growing market demand Gong et al (2020) developed self-healing adhesives based on Schiff base chemistry and addition-fragmentation chain transfer (RAFT) polymerization. Firstly, an esterification reaction was run to synthesize ethylcellulose having a basis on macroinitiators.…”

Nano-structured dynamic Schiff base cues as robust self-healing polymers for biomedical and tissue engineering applications: a review

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.

Self‐healing polymer materials have been developed rapidly over the past 20 years, which can replace thermosetting materials to a certain extent, repair damage without manual intervention, prolong service life, and compress usage cost. The self‐healing polymer materials derived from biomass resources can reduce the dependence on traditional non‐renewable resources such as petroleum. The structures and properties of biomass based self‐healing polymer materials are of great significance for their processing, recycling and self‐healing. In this paper, the research progress of bio‐based self‐healing polymer materials based on dynamic non‐covalent bonds and dynamic covalent bonds including hydroxyl ester, Schiff base, disulfide bond, and hydroxyl urethane derived from vegetable oil, lignin, cellulose, vanillin and natural rubber were reviewed, and the dynamic non‐covalent bonds and dynamic covalent bonds were also introduced. The applications of various dynamic covalent bonds and dynamic non‐covalent bonds in the design and construction of polymer materials were reviewed, and the future development of dynamic covalent polymer materials was prospected.
