Cross-Linked Polymer Hydrogel Electrolytes for Electrochemical Capacitors [PDF]

Journal of The Electrochemical Society, 2006
Acidic polyvinyl alcohol/polyacrylic acid blend hydrogel electrolytes (BHEs) were prepared by cross-linking with glutaraldehyde and perchloric acid. These acidic BHEs were treated suitably to realize alkaline and neutral BHEs. Amorphicity of BHEs was followed by differential scanning calorimetry.
