The silk protein ion elastomers were achieved through a casting solution and high-humidity induction technology by Shanghai Tech University. SRIR microspectroscopy was used to characterize the ion elastomers of the silk fibroin. The secondary structure of the protein was determined by integrating the characteristic peak (amide I) of silk fibroin. After three days of high-humidity treatment, the β-sheet structure was approximately only 20%. This method effectively solves the material-hardening problem. High-humidity treatment, as a mild and controllable induction method, significantly improves the tensile strength of silk protein-ion elastomers. (Advanced Functional Materials, 2023, 33: 2301404)
