a Schematic illustration of strain-stiffening behavior of CPAMC hydrogel. b Comparison of adhesion strengths of our CPAMC in gluing glass with the literature values13,33,54. c Adhesive strength of CPAMC hydrogel in glass in air condition with different contact time. d Mechanical strength of CPAMC hydrogel in glass in air condition with different contact time. e Statistical analysis of adhesive strength and mechanical strength of CPAMC hydrogel in glass in air condition with different contact time (error bar means the standard deviation, *p < 0.05, **p < 0.01, ***p < 0.001, p value was generated by one‐way analysis of variance (ANOVA), followed by Tukey’s multiple‐comparison post hoc test, n = 3 independent samples). f Schematic diagram of dissociation of CPAMC hydrogel triggered by GSH. g Picture of dissociation of CPAMC hydrogel triggered by GSH. CAP, CPAM, CPAMC: C, aldehyde cellulose (CNC-CHO); P, polyethylenimine (PEI); A, acrylic acid; M, 3-sulfonic acid propyl methyl acrylic acid potassium (MASEP); C, caffeic acid (CA).
