Both Cu and Ag possess excellent electrical and thermal properties, while Ag migration and Cu oxidation can be also effectively inhibited. Due to the reversibly variable optical properties of PANI by its unique redox processes, the electrochromic supercapacitor presented herein can display the energy storage level by its visible color and also by its temperature in the absence of light. In terms of materials for EMC, CuAg core-shell powder by plating Ag on surface of Cu powder is a promising candidate to form CuAg solder preforms. To functionalize the metallic nanowire network, we electrodeposited PANI such that the resultant nanowire network can operate as an electrochromic supercapacitor device. By laminating the silver nanowires (AgNWs) with gold and subsequent laser sintering, we fabricated a highly conductive nanowire network electrode. Copper NPs were widely used in optical, catalytic, and electrical fields because of their low cost and high conductivity. In this study, we demonstrate an Ag–Au-PANI multilayered core–shell nanowire network that works both as an electrochromic supercapacitor and visible-to-infrared multispectral display. For technology, coreshell means that the cheaper metal at the core of the bimetallic system, meanwhile the outer shell (a more expensive one) as the protective material to passivate the core-metal, generally oxidation. The intriguing electrochemical properties of polyaniline (PANI) have enabled the functionalization of other nanomaterials and facilitated the development of various smart devices. In the present work, Ag/ZnO core/shell nanostructures are prepared by chemical reduction, and their photocatalytic activity against methylene blue (MB) dye is investigated under visible light with different pH values, annealing temperatures, and PEC properties. The spherical CuAg coreshell nanoparticles are synthesised by one-step wet chemical method. ![]()
