“…Over the past decades, transparent conducting materials (TCMs) have attracted significant attention because of their numerous applications, such as touch panels, organic light emitting diodes (OLEDs), solar cells, and heaters. , Among the TCMs, silver nanowire (AgNW) which exhibits superior optoelectrical performance and high flexibility has been under consideration to replace indium tin oxide (ITO) in the next generation of flexible electronic devices. − Pristine AgNW film generally suffers from large contact resistance, high surface roughness, poor adhesion to the substrate, and so forth. These issues have been addressed by many approaches, including mechanical pressing, embedding AgNWs into or blending with polymers, , introducing additional conductive materials, − forming metal oxide (MO) or metal matrix layer, − and so forth.…”

Instability of silver nanowire (AgNW) has been regarded as a major obstacle to its practical applications in optoelectrical devices as transparent electrodes. Physical barrier layers such as polymer, metal, and graphene have been generally employed to improve the stability of AgNW in previous study. Herein, we first report self-assembled organothiols as an inhibitor for AgNW to achieve an overall enhancement in antioxidation, antisulfidation, thermal stability, and anti-electromigration. The self-assembled monolayers (SAMs) of phenyl azoles, methoxy silane, and methyl alkane were formed on the surface of AgNW via Ag−S covalent bond as barrier layers which provided protective effects against corrosives (e.g., O 2 , H 2 S). In particular, the decoration of 2-mercaptobenzimidazole (MBI) offered the best resistance to H 2 S and excellent stability under a high-temperature and high-humidity environment (85 °C and 85 RH %) for 4 months. Moreover, different SAMs exhibited a stabilizing or destabilizing effect on Plateau−Rayleigh instability of AgNW, which realized the tunability of degradation temperature of AgNWs, for example, increasing by ≥100 °C with MBI SAM or decreasing by ∼50 °C with octadecanethiol SAM compared with pristine AgNWs. Notably, the MBIdecorated AgNWs could survive at 400 °C which is by far the highest bearing temperature for solution-processed AgNW film. As a result, a transparent heater made of the MBI-AgNWs exhibited superior heating characteristics (higher working temperature and durability), as compared with the pristine AgNW-based heater. Our findings on the organothiols decoration not only provide a new paradigm in overall stability improvement of NW of noble metals but also show the potential in morphology controllability of metal NW.

“…They also may be used to enable sensors and biosensors to detect different chemical and biochemical components [30][31][32] or as wearable electronic devices as strain, pressure, and human activity sensors [33][34][35][36]. Moreover, they may be used to create transparent conductive electrodes for applications such as solar cells, LCDs, LEDs, and touch screens [37][38][39][40][41][42][43][44][45][46][47]. Finally, there are challenges and drawbacks in using the alternative material Indium Tin Oxide (ITO) which is chemically unstable, increasing in cost with a limited supply of indium, and in some applications, forms brittle films.…”

Silver nanowires (AgNWs) have a broad range of applications including nanoelectronics, energy conversion, health care, solar cells, touch screens, sensors and biosensors, wearable electronics, and drug delivery systems. As their characteristics depend strongly on their size and morphology, it is essential to find the optimal and most cost-effective synthesis method with precise control over the size and morphology of the wires. Various methods for AgNW synthesis have been reported along with process optimization and novel techniques to increase the yield and aspect ratios of synthesized AgNWs. The most promising processes for synthesis of AgNWs are wet chemical techniques, in which the polyol process is low cost and simple and provides high yield compared to other chemical methods. Reaction mechanism is one of the most important factors in strategies to control the process. Our purpose here is to provide an overview on the main findings regarding synthesis, preparation, and characterization of AgNWs. Recent efforts in the polyol synthesis of AgNWs are summarized with respect to product morphology and size, reaction conditions, and characterization techniques. The effect of essential factors such as reagent concentration and preparation, temperature, and reaction atmosphere that control the size, morphology, and yield of synthesized AgNWs is reviewed. Moreover, a review on the novel modified polyol process and reactor design such as continuous millifluidic and flow reactors to increase the yield of synthesized AgNWs on large scales is provided. The most recent proposed growth mechanisms and kinetics behind the polyol process are addressed. Finally, comparatively few available studies in green and sustainable development of 1D silver nanostructures through the application of natural products with inherent growth termination, stabilization, and capping characteristics are reviewed to provide an avenue to natural synthesis pathways to AgNWs. Future directions in both chemical and green synthesis approaches of AgNWs are addressed.

Thin‐film devices are widely utilized for flat‐panel displays, and the essential advantages of the thin‐film devices are generally large‐area production, various‐material substrate, layered structure, etc. Appropriate applications are flat‐panel displays, and other applications where the abovementioned advantages are available and the disadvantages are acceptable are sensor applications. Moreover, if the sensor devices can be made by thin‐film devices that have been already utilized for flat‐panel displays, they can be made without additional cost. Therefore, thin‐film devices are again promising for sensor applications especially for interactive displays. We are investigating sensor applications of thin‐film devices. Particular in this journal paper, we review sensor applications of thin‐film devices originating in display technologies. The various sensors are visible‐light sensor, infrared‐light sensor, temperature sensor, magnetic‐field sensor, etc. Many research results from many research organizations as well as our research laboratory are introduced.
