Mussel‐inspired, coordinate‐crosslinked gels have attracted extensive attention but their adhesive behaviors are still not fully understood. Herein, four mussel‐inspired molecules with different molecular characteristics are synthesized to study their adhesive behaviors. It is demonstrated that their adhesive behaviors are dependent on the environments. For these mussel‐inspired molecules, physiological environment containing relatively low Fe3+ contents is appropriate for achieving high adhesive strength. In addition, the mussel‐inspired molecules with positive charge, high molecular weight, or high catechol substitute ratio benefited for improving adhesive strength, however, only in the appropriate environment. In the inappropriate environments (physiological pH, high Fe3+ contents), the adhesives show similar low adhesive strength. These environment‐dependent adhesive behaviors are due to the poor interfacial adhesive capacity of the adhesives formed in the inappropriate environments. The study uncovers the adhesive behaviors of mussel‐inspired coordinate‐crosslinked gels and thus may further provide valuable evidences in the design of metal‐crosslinked bioadhesives.

贻贝启发的坐标交联生物胶粘剂的环境依赖性胶粘剂行为
贻贝启发的,配位交联的凝胶吸引了广泛的关注,但它们的粘合行为仍未完全了解。本文中,合成了四个具有不同分子特征的贻贝启发分子,以研究其黏附行为。证明了它们的粘合行为取决于环境。对于这些受到贻贝启发的分子,Fe 3+含量相对较低的生理环境适合获得较高的粘合强度。此外,带正电荷,高分子量或邻苯二酚替代比的贻贝启发分子仅在适当的环境中有益于提高粘合强度。在不合适的环境中(生理pH值,高Fe 3+含量),粘合剂显示出类似的低粘合强度。这些与环境有关的粘合行为是由于在不适当的环境中形成的粘合剂的界面粘合能力差所致。这项研究揭示了贻贝启发的配位交联凝胶的粘合行为,因此可能在设计金属交联生物胶粘剂方面进一步提供有价值的证据。
