“…With an increase in [OH − ], we observed a decrease in the NiNW bundle diameter from 426 ± 91 down to 306 ± 57 nm ( Table 2). This effect is very similar to the capping action of polyvinylpyrrolidone in the course of AgNW formation [29]. In that case, the polymer wrapped around the nascent NW and caused the preferential addition of metal nanoclusters from the front, which caused an elongation of NW instead of an increase in bundle diameter.…”

We have demonstrated a convenient method of synthesizing nickel nanowires (NiNWs), which could be easily tuned to produce materials with a carefully defined nanostructure. By varying the concentration of the Ni precursor, pH of the medium or reaction temperature, we directly affected the diameter of the formed product as well as the yield of the process. The obtained material consisted of straight bundles of NiNWs, which revealed powerful catalytic action for the reduction of nitroarenes to appropriate amine derivatives. A selection of substrates were employed and all of them were successfully converted into the corresponding aromatic amine despite the presence of different substituents on the aromatic ring with high yields, even in large scale reactions. The results showed that NiNW-based catalysts could constitute efficient catalytic systems for the synthesis of aryl amines at industrial levels.

“…Although, ethylene glycol is a common reducing agent in the synthesis of AgNW, glycerol was used here as an alternative reducing agent. Glycerol has a higher boiling point (290 ⁰ C) and a higher hydroxyl group content than ethylene glycol which accelerated the wires growth [26,42]. As in other published work, PVP was used to control the growth direction of…”

“…It is well known that for the organic photovoltaic (OPV) device, a transparency of at least 85% and a shee e a ce f e a 15 / a e is needed to fabricate competitive electrical devices. These wires are usually synthesized using the polyol process with ethylene glycol as reducing agent and poly(vinylpyrrolidone) (PVP) as stabilizer [25,26]. In this research, PVP is used as a stabilizer as well as growth enhancer through preferential adsorption on Ag facets leading to the unidirectional growth of the wire.…”

Transparent conductive electrodes were fabricated by the deposition of silver nanowires (AgNW) on various substrates modified by the deposition of polyelectrolyte multilayers (PEM) as primer. The PEM primer films were coated on the glass substrate by the sequential deposition of 7 or 8 layers of poly(diallyl dimethyl ammonium chloride) (PDADMAC) and poly(styrene sulfonate) (PSS) to improve the adhesion of AgNW and produce flexible transparent conducting *Manuscript Click here to view linked References maintaining excellent transparency (85% transmission at 550 nm) even after up to 6 peeling test cycles. Finally, to demonstrate the benefit of this method, poly(ethylene terephthalate) (PET) sheet was coated with PEM primer and AgNW to produce flexible transparent conducting electrode.

“…They synthesized AgNWs up to 10-20 μm in length and 40-50 nm in diameter without addition of salt mediators, chlorides, and template salts by autoclaving mixtures at 197°C for 9 hr. The autoclave step prevents the oxidization of glycerol in air and consequently formation of acrolein and light-yellow polymer [129]. Li et al synthesized AgNWs as long as 160 μm with 40-85 nm diameter with glycerol as a solvent and a reducing agent and heating at 150°C [130].…”

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.
