“…Figure f compares the opto-electrical performance of our AgNW/Chi composite electrodes with featured transparent electrodes reported in literature and commercial ITO. It is shown that our AgNW/Chi composite electrodes prepared with a simple solution process exhibit a comparable electrical performance with commercial ITO-coated glass, which is significantly higher than ITO-coated PET and also superior or comparable to most reported AgNWs composite transparent electrode with graphene, GO, conducting polymer PEDOT–PSS, photoresist, poly(ionic) gel, liquid crystal, and so forth. ,,− It is also much better than our previously reported AgNW/Aa-PDA and AgNW/CaAlg composites, attributing to the improved AgNWs deposition technology to obtain better pristine AgNW and lowered surface roughness to make higher transmittance. The characteristic sheet resistance of AgNW/Chi is 11.4 Ohm sq –1 for transmittance of 90.0%.…”

“…Adoption of inorganic nanoparticles (NPs), such as TiO 2 , SiO 2 , ZnO, and so forth, flattened the surface of AgNW networks via filling the voids among networks, but no specific root-mean-square (RMS) roughness has been released and transparency of AgNW networks reduced with NPs addition. − AgNWs composite with polymer addition generally enables improved surface roughness. For example, polymer encapsulation involving the cured polymer peeling off from AgNWs coated glass to transfer AgNW networks to polymer surface allows low surface roughness and good adhesion simultaneously. − But only the polymer sticking to metal well but releasing from glass easily can survive as a substrate.…”

In this work, a composite silver nanowire (AgNW) transparent electrode that is large-area ultrasmooth without conductivity or transmittance scarifice, removable but with good resistance to both water and organic solvent, is reported. Via a simple low-temperature solution process without complicated transfer steps or additional pressure pressing, a new kind of AgNWs composite with biocompatible and patternable chitosan polymer complex demonstrates a quite low root-mean-square roughness ∼7 nm at a largest reported scan size of 50 μm × 50 μm, which is among the best flat surface. After long-term exposure to both water and organic solvent, it still shows strong adhesion, unchanged transparency, and no obvious conductivity reduction, suggesting a good stability staying on the substrate. Meanwhile, the polymer and silver nanowire in the composite electrode can be damaged via the same process through concentrated acid or base etching to leave off the substrate, allowing a simple patterning technology. Besides, the imported insulating polymer does not lower down the opto-electrical performance, and a high figure of merit close to 300 is obtained for the composite electrode, significantly outperforming the optoelectronic performance of indium-tin oxide (ITO) coated plastics (∼100) and comparable to ITO-coated glass. It shows great advantage to replace ITO as a promising transparent electrode.

“…Despite the fact that the conduction level of both the ITO and AgNW‐based electrodes was similar, the final AgNW‐based smart window could be modulated over a larger transparency range and at lower voltage supply when compared to the similar ITO‐based architecture . Another example of a thermo‐sensitive PDLC smart window using AgNW networks was recently reported by Wee et al In this case, the AgNW network was used as a transparent film heater to transfer heat to the thermo‐sensitive active layer.…”

Transparent electrodes attract intense attention in many technological fields, including optoelectronic devices, transparent film heaters and electromagnetic applications. New generation transparent electrodes are expected to have three main physical properties: high electrical conductivity, high transparency and mechanical flexibility. The most efficient and widely used transparent conducting material is currently indium tin oxide (ITO). However the scarcity of indium associated with ITO's lack of flexibility and the relatively high manufacturing costs have a prompted search into alternative materials. With their outstanding physical properties, metallic nanowire (MNW)-based percolating networks appear to be one of the most promising alternatives to ITO. They also have several other advantages, such as solution-based processing, and are compatible with large area deposition techniques. Estimations of cost of the technology are lower, in particular thanks to the small quantities of nanomaterials needed to reach industrial performance criteria. The present review investigates recent progress on the main applications reported for MNW networks of any sort (silver, copper, gold, core-shell nanowires) and points out some of the most impressive outcomes. Insights into processing MNW into high-performance transparent conducting thin films are also discussed according to each specific application. Finally, strategies for improving both their stability and integration into real devices are presented.

Flexible transparent conductive electrodes (TCEs) are widely applied in flexible electronic devices. Among these electrodes, silver (Ag) nanowires (NWs) have gained considerable interests due to their excellent electrical and optical performances. Ag NWs with a one-dimensional nanostructure have unique characteristics from those of bulk Ag. In past 10 years, researchers have proposed various synthesis methods of Ag NWs, such as ultraviolet irradiation, template method, polyol method, etc. These methods are discussed and summarized in this review, and we conclude that the advantages of the polyol method are the most obvious. This review also provides a more comprehensive description of the polyol method for the synthesis of Ag NWs, and the synthetic factors including AgNO3 concentration, addition of other metal salts and polyvinyl pyrrolidone are thoroughly elaborated. Furthermore, several problems in the fabrication of Ag NWs-based TCEs and related devices are reviewed. The prospects for applications of Ag NWs-based TCE in solar cells, electroluminescence, electrochromic devices, flexible energy storage equipment, thin-film heaters and stretchable devices are discussed and summarized in detail.
