Research progress on the stability of transparent conductive films for silver nanowires.

As a key component in flexible optoelectronic devices, flexible transparent conductive films will become a strategic material in optoelectronic products. Among them, silver nanowire (AgNW) transparent conductive film (TCF) is the most marketable and promising optoelectronic material. However, the nano-size effect makes AgNW TCF less weather-resistant and prone to corrosion in the service occasions, leading to degradation or even failure of the conductivity of optoelectronic devices. Therefore, poor stability is one of the key issues hindering the large-scale industrialization of AgNW TCF. This article focuses on the application scenarios and stability of AgNW TCF: firstly, its related application scenarios in flexible displays, thin-film solar cells, and electromagnetic shielding glass are summarized; then the impact of service environment (environmental pollutants, temperature, humidity, lighting, etc.), mechanical effects, thermoelectric coupling effects on the stability of AgNW TCF are discussed; finally, the optimizing strategies are put forward about how to improve the stability of AgNW TCF. It provides a reference for researchers to improve the stability of AgNW TCF. • It analyzes advantages and limitations of AgNW TCF as a flexible transparent conductive film. • Impact of environmental factors, mechanical action, and thermo-electric coupling effects on stability of AgNW TCF have been discussed. • It looks forward to future research directions of AgNW TCF.
