Supercapacitor behavior of CuO–PAA hybrid films: Effect of PAA concentration

Impact of rare-earth metal oxide (Eu2O3) on the electrochemical properties of a polypyrrole/CuO polymeric composite for supercapacitor applications

“…23 On the other hand, transition metal oxides, such as oxides of ruthenium, copper, titanium, and manganese have revealed pertinent potential as electrode material for supercapacitors owing to their high pseudocapacitance value. 7,[24][25][26] Copper oxide (CuO) has drawn global attentions because of its low cost, nontoxicity, rich resources, and ease of synthesis in various nano-sized dimensions. Amongst the family of metal oxides, CuO possessing a low bandgap (1.2 eV) displays p-type semiconductor behavior and is considered to be one of the aptest candidates for supercapacitor electrode material due to its excellent pseudocapacitive properties.…”

CuO synthesized in various structures have been explored to be used as supercapacitor electrode.…”

Poly(Acrylic acid)–Based Hybrid Inorganic–Organic Electrolytes Membrane for Electrical Double Layer Capacitors Application

“…PAA is a non-toxic, hydrophilic and biocompatible superabsorbent polymer with a three dimensional (3-D) network [ 16 , 17 , 18 ]. PAA was chosen as a host polymer in this research due to its fascinating behaviors such as excellent stability in acidic and basic media, high ionic conductivity, strong adhesive properties, superior selectivity and permeability and high ability to associate with a variety of multivalent metal ions in solution [ 18 , 19 , 20 , 21 ]. PAA can suppress the crystallization and form stable complexes with metal [ 18 , 22 , 23 ].…”

Layer‐by‐layer supramolecular assemblies based on linear and star‐shaped poly(glycerol methacrylate)s for doxorubicin delivery

“…The first weight loss took place in the temperature range of 50–200°C, yielding a value of 7.2%, which could be the desorption of physically absorbed water molecules. The second weight loss occurred in the temperature range of 200–550°C, a typically high enough temperature to induce thermal degradation of PAA35, 36 and amino‐PGOHMA 37. Judging from Figure 6(a), the remnant of 81.49% in weight of the core‐shell particles indicated that the SiO 2 is the main constitution of the composite particles, which reduced to ∼10% after core‐removing, while the first weight loss in curve (b) is dropped earlier.…”
