“…Arguably, materials with a lower work function that operate at a lower temperature are noted to release more electrons [29] , [30] . Consequently, the work function is of tremendous technological importance in many applications such as thermionic energy converters [31] , [32] , printed and organic electronics [42] , [43] , [44] , emerging perovskite solar cells technology fluorescent light tube [45] , electron emission gadgets (terahertz sources) [46] , [47] , scientific instruments that use electron sources [30] , [39] , [40] , [41] , catalysis [42] , [43] , [50] , [51] , electrochemistry [52] , [53] , [54] , corrosion resistance [25] , [55] , [56] and as an interfacial diagnostic tool in material [57] . These novel applications are realizable if the materials are mechanically, chemically and thermally stable (thoriated tungsten and lanthanum hexaboride), preferably caesiated metals of low work function [48] , [49] , [58] , [59] , as applied in thermionic energy converter [38] , [60] , [61] , [62] , [63] .…”

“…The oxidation stability of AgNW-based TCEs under the thermal and chemical conditions was also improved by growing monolayer graphene onto the pristine AgNWs using the chemical vapor deposition (CVD) method . Besides, metal or metal oxide deposited on AgNW electrodes by an atomic layer deposition (ALD) method is another way to enhance the electrical conductivity and thermal oxidation stability. − Apart from coating passivation layers onto the AgNW electrodes, functionalizing the AgNWs with strongly bound ligands could enhance their stabilities. − However, the aforementioned approaches are relatively technical, have a high cost, and make sacrifices of optoelectrical performance to some extent, which would hinder their adoption for commercial applications.…”

Silver nanowires (AgNWs) have emerged as a greater promising material for transparency-based electrodes compared to indium-tin-oxide (ITO) electrodes because of the tunable figures of merit, large-scale processability, and flexibility. However, they still suffered from a crucial problem of instability under the thermal condition, mechanical stimuli, and particularly sustained electrical currents, which is a challenge persisting to date. Here, we demonstrate the improved electrochemical stability of AgNWs by a simple cost-effective electroactive triphenylamine (TPA)-based polymer film as a passivation layer onto the AgNW networks. The AgNW/TPPA hybrid electrode could not only enhance the overall performance including electrical oxidation stability and adhesion to the substrates but also has little effect on transparency contrary to typical passivation films. Besides, the electrochromic behaviors of the obtained AgNW/TPPA hybrid electrode demonstrated obvious multicolor appearance changes during their two oxidation stages. Finally, the AgNW/TPPA hybrid was fabricated as an electrochromic device (ECD) according to the ambipolar conduction behavior. The fabricated ECDs were also used in cyclic and differential pulse voltammetry techniques at a wide-range applied potential for continuous 300 switching cycles, which signifies that our proposed method has long-term operational stability. Thus, our fabrication strategy platform should enable an improved pathway to the development of optoelectronic devices and offer considerable promise for addressing growing concerns of device stability.

“…Great attention has been devoted to various flexible and transparent heaters (or electrodes) based on printed electronics due to different reasons such as devices having nonplanar and flexible substrates, the potential scarcity of indium, and the lack of transparency in the near-infrared spectrum [ 6 , 7 , 8 ]. In these printed electronic products, conductive materials with low resistance, high transmittance, high flexibility, etc., are essential in the performance of the devices, and various conductive materials such as transparent conductive oxide, metallic nanowires, conductive polymers, and carbon-based electrodes have been investigated [ 9 , 10 , 11 , 12 , 13 , 14 ].…”

Transparent heat films (THFs) are attracting increasing attention for their usefulness in various applications, such as vehicle windows, outdoor displays, and biosensors. In this study, the effects of induction power and radio frequency on the welding characteristics of silver nanowires (Ag NWs) and Ag NW-based THFs were investigated. The results showed that higher induction frequency and higher power increased the welding of the Ag NWs through the nano-welding at the junctions of the Ag NWs, which produced lower sheet resistance, and improved the adhesion of the Ag NWs. Using the inductive welding condition of 800 kHz and 6 kW for 60 s, 100 ohm/sq of Ag NW thin film with 95% transmittance at 550 nm after induction heating could be decreased to 56.13 ohm/sq, without decreasing the optical transmittance. In addition, induction welding of the Ag NW-based THFs improved haziness, increased bending resistance, enabled higher operating temperature at a given voltage, and improved stability.
