The paper reports the synthesis and characterization of an Ag₂WO₄/PANI composite via in-situ polymerization. The composite was prepared by combining silver tungstate (Ag₂WO₄) and polyaniline (PANI) through a chemical polymerization process. The as-synthesized material was characterized using various spectroscopic and analytical techniques. Electrochemical performance was evaluated using cyclic voltammetry (CV), which revealed a specific capacity of 827 C g⁻¹ at 5 mVs⁻¹ and a capacity retention of 93% after 5000 GCD cycles at a current density of 1 Ag⁻¹. The study highlights the potential of Ag₂WO₄/PANI as an alternative electrode material for energy storage systems, particularly supercapacitors, due to its high specific capacitance and good cycle stability. The research also discusses the advantages of combining transition metal oxides with conducting polymers to enhance the electrochemical properties of the composite.The paper reports the synthesis and characterization of an Ag₂WO₄/PANI composite via in-situ polymerization.
