“…Nanosized metals are reactive in atmospheric oxygen and water because of their large surface-to-volume ratios. Our nanowires and others 33 , 34 , 60 are between 500 and 1000 nm, which is larger than many literature examples of < 100 nm 29 , 61 – 63 . The larger diameter of our materials yields enhanced chemical durability.…”

Transparent conducting electrodes (TCEs) are essential components in devices such as touch screens, smart windows, and photovoltaics. Metal nanowire networks are promising next-generation TCEs, but best-performing examples rely on expensive metal catalysts (palladium or platinum), vacuum processing, or transfer processes that cannot be scaled. This work demonstrates a metal nanowire TCE fabrication process that focuses on high performance and simple fabrication. Here we combined direct and plating metallization processes on electrospun nanowires. We first directly metallize silver nanowires using reactive silver ink. The silver catalyzes subsequent copper plating to produce Ag–Cu core–shell nanowires and eliminates nanowire junction resistances. The process allows for tunable transmission and sheet resistance properties by adjusting electrospinning and plating time. We demonstrate state-of-the-art, low-haze TCEs using an all-atmospheric process with sheet resistances of 0.33 Ω sq−1 and visible light transmittances of 86% (including the substrate), leading to a Haacke figure of merit of 652 × 10–3 Ω−1. The core–shell nanowire electrode also demonstrates high chemical and bending durability.

“…where η is the viscosity of the solution, L is the length of AgNWs, and V is the coating speed. In AgNW:HPMC solution, the concentration of HPMC determines the viscosity of the solution and has a very important effect on the morphology and optoelectronic properties of the prepared AgNW TCFs [26,29].…”

Filter cloth brush-coating (FCBC), using soft filter cloth as a brush-coating medium, in conjunction with viscous silver nanowire (AgNW) conductive solution, is used to prepare AgNW conductive films. The density and uniformity of AgNWs deposited on the substrate are controlled by the interplay between the filter cloth aperture, the conductive solution viscosity, and the brush-coating speed. Further, with appropriate AgNW concentration and flow rate, uniform AgNW transparent conductive film with sheet resistance of 18 Ω/sq and transmittance of 94% at 550 nm is acquired by FCBC. Due to the precise control of the coating process in FCBC, large-area uniform AgNW conductive film fabricated on printing paper has a low non-uniformity factor of 1.2% at a sheet resistance of 19.0 Ω/sq. The resultant paper-based AgNW film heater shows sensitive and stable heating performance. FCBC shows great potential in producing large-area uniform AgNW films on various substrates.

“…Nanosilver with different morphologies, such as particles, sheets, and wires, has been widely used in the preparation of conductive inks [11][12][13]. Among them, silver nanowires (AgNWs) are one of the most promising ink materials owing to their excellent electron conductivity and resistance to bending and stretching [14]. Generally, AgNW conductive inks are synthesized by hydrothermal [15], template [16], and polyol methods [17].…”

Conductivity enhancement of Ag nanowire ink by decorating in situ formed Ag particles under low-temperature sintering

Silver nanowires (AgNWs) have attractive applications in the fabrication of flexible electronics because of their adequate electrical conductivity, mechanical properties, and oxidation resistance. However, the film produced by AgNW ink needs to be sintered at temperatures above 200 °C to obtain high electrical conductivity, which is incompatible with commonly used flexible substrates such as paper or polymer materials. In this study, the AgNW network was decorated by in situ reduced Ag particles (AgPs) to improve the structural integrity and conductivity of the film. After sintering at 80 °C, the pores and voids within the AgNW network were filled with Ag particles smaller than 200 nm, and the porosity of the film was markedly reduced. The lowest resistivity value was 3.9×10-5 Ω•cm after sintering at 100 °C, only 10.8% and 8.5% of the resistivity values of the films produced from AgNW and ion inks, respectively. During sintering, Ag nucleated on the surface of AgNWs, and its growth and agglomeration resulted in interconnections between the AgNWs and Ag particles. Thereafter, the bridging and filling effect of the Ag particles facilitated the formation of a compact and firm network, improving the film conductivity. The line film printed from the composite ink with 10 layers exhibited a low resistivity of 7.3×10-7 Ω•m. Even after 5000 bending cycles, the resistivity of the line only increased by 4.47×10-6 Ω•cm from the initial value. The composite ink reported in this study is a promising candidate for the low-cost printing of ultralow-power-consumption wearable electronic devices.
