Enhanced stability of silver nanowire transparent conductive films against ultraviolet light illumination

Abstract

Silver nanowires are susceptible to degradation under ultraviolet (UV) light illumination. Encapsulating silver nanowire transparent conductive films (AgNW TCFs) with UV shielding materials usually result in the increasing of the sheet resistance or the decrease of the visible light transparency. Herein, we combine a reducing species (FeSO4) and a thin layer (overcoating) of UV shielding material to solve the stability and the optical performance issues simultaneously. The AgNW TCFs show excellent stability under continuous UV light illumination for 14 h, and their sheet resistance varies only 6%. The dramatic enhancement of the stability against UV light illumination for as-obtained TCFs will make them viable for real-world applications in touch panels and displays.

Multifunctional Flexible AgNW/MXene/PDMS Composite Films for Efficient Electromagnetic Interference Shielding and Strain Sensing

“…AgNWs, a typical conductive material, are commonly used to construct functional composites for EMI shielding or strain sensing owing to their high aspect ratio and excellent mechanical stability. ,,, However, the high contact resistance and loose spatial connections between the one-dimensional AgNWs limit their performance . Fortunately, two-dimensional MXene materials exhibit good metallic conductivity and can fill the spatial voids between AgNWs. , Furthermore, the abundant reactive end groups on the MXene surface enable them to interact with AgNWs through hydrogen bonding, resulting in enhanced stability. ,, Therefore, developing an efficient structure that combines the advantages of AgNWs and MXene remains a challenge, especially in the preparation of composite films with excellent EMI shielding and strain sensing properties.…”

Accelerated and outdoor weathering of silver nanowire transparent conductors under electrical stress in pseudo-modules

“…Heat, moisture, visible light, ultraviolet (UV) irradiation and gaseous corrosive chemical species [4][5][6][7][8][9] along with the essential electrical stress [9][10][11][12] are major stressors that degrade AgNWs. Applying overcoating of inorganic oxide [12,13] and polyacrylic resin [14] dramatically enhance the stability of AgNWs against the electrical stress and UVA exposure, respectively [15]. On the other hand, simply encapsulating AgNWs by pseudo-module drastically protects them from the damages of damp heat (85 °C and 85% relative humidity (RH)) and UVA/75 °C exposure [16].…”
