“…Efforts have been devoted into synthesizing UTAgNWs, for example, a high-pressure hydrothermal process was proposed to synthesize AgNWs with a diameter in the range of 15–20 nm, − a magnetic ionic liquid-assisted polyol method was used to synthesize UTAgNWs with an average diameter of 20 nm, benzoin-derived radicals were employed as a mild reducing agent to synthesize UTAgNWs with an average diameter down to 13 nm, and a light-emitting diode illumination-stimulated growth method was reported to synthesize UTAgNWs with diameter further down to 9 nm . It is still difficult to scale-up the production of UTAgNWs using these methods.…”

Ultrathin silver nanowires (UTAgNWs) are indispensable to achieve transparent conductive films (TCFs) with overall optoelectronic performance exceeding that of the state-of-the-art indium tin oxide films. Impurities in raw UTAgNW products severely impair the optical properties of TCFs. Unfortunately, highly effective and environment-friendly approaches for purification of UTAgNWs are still lacking. Herein, we report the purification of UTAgNWs using deionized water along with a small amount of surfactants as the purifying agent. TCFs coated with the purified UTAgNWs exhibit a light transmittance of 97.9% and a haze of 1.22% at a sheet resistance of 36.3 Ω sq–1 or a light transmittance of 99.8% and a haze of 0.47% at a sheet resistance of 187.3 Ω sq–1. Both the transmittance and the haze are among the best reported values for AgNW TCFs in the literature. The purification process does not involve any toxic or hazardous chemicals and is both scalable and cost-effective.

“…Herein, Ag NWs with a diameter of 25 nm and aspect ratios as high as 1500 were directly synthesized through the modified polyol method via the via the chemical reduction of AgNO 3 (Aldrich) in the presence of a magnetic ionic liquid, 1-butyl-3-methylimidazolium tetrachloroferrate (bmim[FeCl 4 ]), using a previously reported method [ 26 ]. The synthesized Ag NWs were dispersed in an aqueous solution (0.3 wt % in H 2 O) with a polyvinylpyrrolidone (PVP) (average molecular weight, Mw = 1,300,000, Aldrich, St. Louis, MO, USA) polymer surfactant.…”

Highly stable and durable conductive silver nanowire (Ag NW) network electrode films were prepared through decoration with a 5-nm-thick Ti layer. The Ag NW network 2-D films showed sheet resistance values as low as 32 ohm/sq at 88% transparency when decorated with Ti. These 2-D films exhibited a 30% increase in electrical conductivity while maintaining good stability of the films through enhanced resistance to moisture and oxygen penetration as a result of the protective effect of the Ti layer.

“…Finally, the supernatant was collected to obtain an acid-treated pure SWCNT mono-disperse solution. Ag NWs with an average diameter of 20 nm and a length of 20 µm were directly synthesized according to the magnetic-ionic-liquid-assisted polyol process [34]. As-synthesized Ag NW was re-dispersed in 0.5 wt% DI water and prepared in an aqueous suspension solution.…”

We report the fabrication of stretchable sensor films (SSF) using a composite of functionalized polypyrrole- single-walled carbon nanotube (SWCNT)-silver nanowire hybrid networks embedded into a cross-linked polydimethylsiloxane elastomer. The SSF exhibited low resistivity of 30 Ω/sq and an outstanding mechanical elasticity of up to 25% (no visible change in the sheet resistance after 100 cycle at stretching-release test of 25%). These SSFs were responsive to 1 ppm ammonia gas even at a low temperature of 40 °C with 20% relative humidity and also maintained reproducibility and reversibility when repeatedly exposed to ammonia gas more than 100 times. In addition, it was confirmed that the sensor film was hardly affected even at a relative humidity range of 20% to 80%.
