Enhanced stretchability and robustness towards flexible ionotronics via double-network structure and ion-dipole interactions

Ionic conductive gels enabled by ionic liquids (ionogels) are promising candidates for flexible electronics due to less concerns on liquid evaporation and leakage. However, it is still a challenge to simultaneously enhance the strength and stretchability for an ionogel. Here, we report a mechanically robust and stretchable ionogel, employing fluorinated acrylic monomers to construct double network (DN) structure and ion-dipole interactions …
