Degradation Mechanism of Silver Nanowire Transparent Conductive Films: a Review

Abstract

Silver nanowire transparent conductive film is one of the new indium-free electrode materials. It has attracted increasing attention from academia and industry due to its superior optoelectronic properties and excellent flexibility. It has been employed in a wide variety of applications in displays, touch panels, solar cells, smart heaters, electromagnetic interference shielding, and so on. However, silver nanowire transparent conductive film has a serious stability issue in service, for example, break or spheroidization above 300 ℃ under fulfidation, accelerating the degradation under ultraviolet light, pores formation or even breakdown due to electromigration. In this review, the degradation phenomena is thoroughly introduced, the degradation mechanisms is analyzed, and the remedy strategy of degradation is discussed.

Preparation and Performance of AgNWs/PDMS Film-Based Flexible Strain Sensor

“…A silver nanowire (AgNW) is a single crystal structure with an average diameter of 20–100 nm and average length of 20–200 μm, with a similarly high electrical conductivity (6.3 × 10 −7 S·m −1 ) and thermal conductivity (429 W·m −1 ·K −1 ) to silver [ 15 ]. AgNWs are usually prepared via the polyol reduction method, and the aspect ratio can be adjusted in a certain range, while the yield and purity are also improved steadily.…”
