The Preparation of Electrolyte Hydrogels with the Water Solubilization of Polybenzoxazine

The Preparation of Electrolyte Hydrogels with the Water Solubilization of Polybenzoxazine
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.

Manganese Oxide Supercapacitor with Aqueous Hydrogel Electrolyte

ECS Transactions, 2008
Two poly(acrylic acid)-based gel electrolytes have been characterized for their application to MnO2•nH2O supercapacitors. The gel polymer electrolytes (GPEs) consist of either poly(acrylic acid) or poly (acrylic acid)-co-poly(acrylamide) with 1 M KCl aqueous solution (weight composition, polymer : KCl : H2O = 9%: 6.7%: 84.3%). The GPEs show no fluidity,
