Resistance of silver nanowires
A percolation model gives R s = R n (c ¯) − 2, where c ¯ is the mean network coverage and R n is the network resistance, determined by the dimensions and electrical resistance of the individual nanowires. Network resistance is independent of coverage and increases with strain cycles, showing two clear regimes following the onset of damage after about 100 cycles. Silver nanowires with high length- diameter ratio could reduce intraparticle resistance, and the tunnel resistance caused by the tunnel effect has little influence of ECAs filled with silver flakes and nanowires, so the increase of resistance is mainly associated with contact resistance in the system. Networks of silver nanowires appear set to replace expensive indium tin oxide as the transparent conducting electrode material in next generation devices. The success of this approach depends on optimizing the material conductivity, which until now has largely focused on minimizing the junction resistance between wires. In general, silver nanowires are easily dispersed in an ethylene glycol, isopropyl alcohol and deionized (DI) water solution with the addition of organic binders as dispersants and adhesive agents To begin with, silver nanowires do their job better than competing materials boasting high transmission rates and low resistance. This combination enables 10-finger touch, brighter displays, and longer battery life—all critical elements in improving the user experience.

A method to produce scalable, low‐resistance, high‐transparency, percolating networks of silver nanowires by spray coating is presented. By optimizing the spraying parameters, networks with a sheet resistance of R s ≈ 50 Ω −1 at a transparency of T = 90% can be produced. The critical processing parameter is shown to be the spraying pressure.
Electrodes with higher sheet resistances and electrodes subject to higher current densities fail more quickly. The reason for electrode failure is attributed to the instability of silver nanowires at elevated temperatures caused by Joule heating. Design factors such as passivation, electrode sheet resistance, Synthesis and highly effective purification of silver nanowires to enhance transmittance at low sheet resistance with simple polyol and scalable selective precipitation method† Molla Bahiru Gebeyehu , Tolesa Fita Chala , Shao-Yen Chang , Chang-Mou Wu and Jiunn-Yih Lee * Department of Materials Science and Engineering, National Taiwan University of Science and Technology, Taipei 10607, Taiwan, Republic of China. temperatures, wherein the lateral growth of silver nanowires is restrained because of efficient surface passivation. The optoelectronic performance of as-prepared 13 nm silver nanowires presents a sheet resistance of 28 Ω sq−1 at a transmittance of 95% with a haze factor of ∼1.2%, comparable to that of commercial indium tin oxide (ITO). Silver nanowires (Ag NWs) possess excellent optoelectronic properties, which have led to many technology-focused applications of transparent and flexible electronics. Many of these applications Fig. 2 SEM images of silver-nanowire-coated (a, b) nylon thread, (c, d) cotton thread and (e, f) polyester thread. In the SEM images, the nylon thread ( Fig. 2a and b) was dipped 3 times in a solution containing 1.25 mg mL −1 of silver nanowires in ethanol and has a resistance of 12 ω cm −1. Conductive and transparent coatings consisting of silver nanowires (AgNWs) are promising candidates for emerging flexible electronics applications. Coatings of aligned AgNWs offer unusual electronic and optical anisotropies, with potential for use in micro-circuits, antennas, and polarization sensors.
