Facile synthesis of very-long silver nanowires for transparent electrodes

Abstract

Silver nanowires >60 μm have been synthesized using a polyol process without stirring at 130 °C.

Comprehensive Synthesis Study of Well-Dispersed and Solution-Processed Metal Nanowires for Transparent Heaters

“…When compared to the synthesis shown in Figure 2(e), which will be denoted as the reference synthesis in the following, the length of the wire decreases drastically from 44. has previously been reported and attributed to a mechanical interruption of the wire growth [33,34]. For the change in diameter with stirring speed, there are studies that report no dependency on the stirring speed [34] or even a reduction [33]. In our case, the aspect ratio is significantly lowered, as shown in the inset of Figure 3(e).…”

“…Figure 3 shows the SEM images for (a) 10 min stirring during a total process time of 30 min at a stirring rate of 260 rpm and stirring throughout the entire process time at a rate of (b) 260 rpm, (c) 500 rpm, and (d) 1000 rpm.

“…After the effect of stirring during the growth was studied, the influence of the precursor to capping agent weight ratio, that is, the AgNO 3 to PVP weight ratio, was investigated. For the capping agent, we chose PVP with an average molecular (MW) weight of 360 kgmol −1 , referred to as PVP360k in the following, which is frequently reported in the literature for the polyol-based synthesis of AgNWs [28,34,[38][39][40]. Besides, for PVP360k, numerous synthesis protocols have been proposed that employed PVPs with a different average MW that in turn corresponds to a different average chain length.…”

Sub 30 nm silver nanowire synthesized using KBr as co-nucleant through one-pot polyol method for optoelectronic applications

“…It requires no stirring, dropwise adding reactant and other actions, which improved the repeatability and has been increasingly applied in recent works [15][16][17]. Although nanowires of diameter around 50 nm can been prepared in large scale now, ultrathin (<30 nm) AgNW prepared in solution through one-pot polyol method is still difficult and has rarely been reported [17], which limited its applications in optoelectronic devices.…”

Facile fabrication of stretchable Ag nanowire/polyurethane electrodes using high intensity pulsed light

“…AgNWs of two lengths were used in this work, which were synthesized according to a previously reported method at 110 °C for 12 h for long NWs, and 150 °C for 2 h for short NWs [38]. The long NWs measured 30-60 μm in length and 85 nm in diameter, and the short NWs were 10-20 μm in length and 70 nm in diameter.…”
