Silver Nanowire Synthesis and Applications in Composites: Progress and Prospects

Abstract

Silver nanowires (AgNWs) have gained increased interest as highly conductive and transparent nanomaterials with numerous applications across various fields. Owing to their unique properties (e.g., optical transparency, electrical conductivity, mechanical characteristics, and ease of processing), AgNWs have been extensively investigated for application in light‐emitting diodes, solar cells, electrocatalysis, liquid crystal displays, wearable electronic devices, flexible nanosensors, and supercapacitors. In this review, recent advances in the synthesis of AgNWs (including the polyol, template, wet chemical, and photoreduction methods) are discussed, with a focus on their advantages and disadvantages in terms of AgNW structural regulation. Furthermore, the advantages and applications of AgNW composites, are comprehensively reviewed and analyzed, with a focus on energy storage and optoelectronics, sensors, electromagnetic interference shielding and absorbing materials, nanogenerators, and other applications. The prospects and challenges of AgNW composites in emerging applications are also proposed.

“…Among these alternatives, silver generates high interest as it exhibits an electrochemical behavior close to that of ruthenium oxide, is cheaper than ruthenium oxide, and is more environmentally sustainable. , Also, silver in its different oxidation states (AgO, Ag 2 O, and Ag 2 O 2 ) is more conductive than other transition-metal oxides investigated for pseudocapacitor applications and has more ability to change and adopt different oxidation states (+1, +2), providing the energy storage ability. Furthermore, from the electrochemical perspective, silver is very reactive and forms different oxide phases such as AgO, Ag 3 O 4 , Ag 4 O 3 , Ag 2 O 3 , and Ag 2 O, where Ag 2 O is the most stable among them. − In addition, silver has been used in previous studies as a component of electrodes; also, silver nanowires are commonly used in flexible and wearable electronic devices.
