The Study of Polyacrylamide-ZnO Composite as Electrode in Electrochemical Supercapacitor

In this study, polyacrylamide-ZnO composites were synthesized and the behavior of the obtained composites were studied as electrode materials in electrochemical supercapacitors. The morphology, crystal structure, and thermal stability of the composites were examined by Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), Thermal Gravimetric Analysis (TGA), and FT-IR. Electrochemical properties were determined by Cyclic Voltammetry (CV). Cyclic voltammetry curves confirmed the reversible electrochemical behavior of the composites. The composite oxide content was found to be 15% of the composite’s capacity, with 30% and 50% for zinc oxide. The results indicated that although presence of zinc oxide in the composite has effective role on the electrochemical behavior of the composite, the morphology and thermal stability of the composite determined the composite’s capacity as an electrode in electrochemical supercapacitors.
