| 摘要 | Conventional tannin-based adhesives have limitations such as formaldehyde emission, inadequate strength and toughness, which restrict their practical applications. Herein, motivated by the natural mechanisms of ‘phenol-amine’ cross-linking and biomineralization, a strong, tough and formaldehyde-free tannic acid-based adhesive was prepared by using all-biomass feedstock. The adhesive was prepared by integrating tannic acid-Zn nanoparticles (TA-Zn NPs), hyperbranched polyamide-grafted dialdehyde chitosan (HPCS), and triglycidylamine (TGA), which formed the fundamental cross-linking network of the prepared adhesive through a Schiff base reaction. The dry and wet bonding strength of the adhesive achieved 1.91 MPa and 1.54 MPa, respectively. The presence of sacrificial bonds such as N…Zn complexation and hydrogen bonding in the adhesive significantly enhance its toughness with a debonding work of 0.595 J. Benefiting from the exceptional antimicrobial properties of TA, chitosan, and Zn2+, the prepared adhesive demonstrated excellent mechanical properties even after being stored in a humid environment for 2 days, with wet and dry bond strength of 1.42 MPa and 1.10 MPa, respectively. Moreover, this adhesive exhibited remarkable resistance to mildew for a duration of 30 days and emitted lower volatile organic compounds compared to other synthetic and biomass adhesives. This innovative bionic strategy holds great potential in enhancing the toughness and functionality of adhesives and composites. © 2024 Elsevier Ltd |

| 资助项目 | The chemical structures of the HPCS were analysed by using FTIR spectroscopy (Fig. 3b). In the spectrum of CS, a broad and strong peak near 3420 cm−1 indicated the stretching vibrations of O−H and N−H (Javaid et al., 2020). The absorption peak at 1650 cm−1 represented the stretching vibration of C=O, which was significant enhanced in DACS compared to that in CS. This enhancement indicated the successful generation of double aldehyde groups (León et al., 2018). In the spectrum of DACS, the decrease of the C−C peak at 1400 cm−1 and the change in the shape of the O−H peak near 3436 cm−1 indicated the opening of the pyranose ring at the C−C positions (Wegrzynowska-Drzymalska et al., 2020). The absorption peaks at 1660 and 1570 cm−1 in the HPCS spectrum indicated the presence of C=N and C=O groups. This supported the occurrence of Schiff base reactions between the aldehyde group on DACS and the primary amine group on HBPN (Liu et al., 2016). These changes in characteristic peaks confirmed the successful grafting of HBPN to DACS. The possible reaction mechanism for the preparation of HPCS is shown in Fig. 3a.This work was financially supported by the National Natural Science Foundation of China (32101456 and 32371792), the China Postdoctoral Science Foundation (2022M710598), the China Postdoctoral Science Foundation Special Grant (Pre-station) (2023TQ0374), and the Independent Scientific Research Projects from Jiangsu Province Key Laboratory of Biomass Energy and Materials (JSBEM-S-202309).
