A Synthesis reaction of methacrylated silk fibroin (SFMA) and PIL. B 1H NMR spectra of PIL. C S-PIL gelation after UV light. D Rheology characterizations and E XPS full spectrum of S-Gel with the different concentrations of PIL. F B1s XPS signal of S-PIL10. G Amino II of S-Gel with the different concentrations of PIL in FTIR spectra. H Quantitative analysis of secondary structures of S-PIL10 with Gaussian curve fitting in FTIR spectra. I Multiple interactions between SFMA and PIL in the network. J SEM image and corresponding EDS elemental mapping of S-PIL10. The SEM characterization experiments were conducted three times independently.
