a Schematic diagram of the sample preparation and testing process for lap shear testing. b, c Lap-shear curves and adhesion strength analysis of SFMA microgroove coating on unmodified, normal silk-modified, and SFMA-modified SIS substrates. d, e Lap-shear curves and adhesion strength analysis of the SFMA microgroove coating with 5%, 6%, and 7% concentrations on SFMA-SIS substrates. f, g Lap-shear curves and adhesion strength analysis of the SFMA microgroove with or without water vapor annealing treatment on SFMA-SIS substrates. Values in (c, e, g) represent the mean ± SD (three independent replicates (n = 3)). Statistical difference was determined by two-tailed unpaired Student’s T-test between two groups. One-way analysis of variance (ANOVA) with a Tukey’s post hoc test was used for multiple comparisons. Source data and exact P values are provided as a Source data file. (*P < 0.05, **P < 0.01, ***P < 0.001).
