Polyzwitterionic hydrogel electrolytes via ultrafast autocatalytic gelation process for flexible Zn-Ion hybrid supercapacitors

MXene, protein, and KCl-assisted ionic conductive hydrogels with excellent anti-freezing capabilities, self-adhesive, ultra-stretchability, and remarkable mechanical properties for a high-performance wearable flexible sensor

“… 8 Conductive hydrogels are currently believed to be promising for developing flexible electronics because of their excellent characteristics of mechanical compliance, 9 super stretchability, 10 and high conductivity. 11 However, most hydrogel-based sensors face issues related to non-conductance caused by freezing, consequently significantly hindering their use in low-temperature conditions. Adding low-volatile solvents into the hydrogel is considered an effective approach to increasing its anti-freezing capability.…”
