Electrical and Capacitive Response of Hydrogel Solid-Like Electrolytes for Supercapacitors [PDF]

Polymers, 2021
Flexible hydrogels are attracting significant interest as solid-like electrolytes for energy storage devices, especially for supercapacitors, because of their lightweight and anti-deformation features. Here, we present a comparative study of four ionic conductive hydrogels derived from biopolymers and doped with 0.1 M NaCl.

The Preparation of Electrolyte Hydrogels with the Water Solubilization of Polybenzoxazine

Gels, 2023
Polybenzoxazine (PBZ) exhibits excellent heat resistance, and PBZ derivatives have been designed and synthesized to achieve high performance. However, the application range of PBZ is limited by the strong interactions between molecular chains and its low solubility in organic solvents, thereby limiting its processability.
