Abstract

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.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Since the catechol group can chelate with Fe3+ under weakly alkaline conditions, coordination crosslinking is often used in the design of multiple crosslinked hydrogels.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
