Spider-silk-inspired dynamic hard-soft ionogels enabled by solvation-contrast-guided phase separation.
Stretchable ionogels are promising epidermal biointerfaces, yet integrating mechanical robustness with efficient viscoelastic dissipation remains challenging. Inspired by the hard-soft hierarchical architecture of spider silk, we develop a phase-separated ionogel by copolymerizing N,N-dimethylacrylamide (DMAA) and acry...
