“…This is similar to the case reported by Chen and Tsuji. 39 Therefore, according to the above phenomena and analysis, a plausible growth mechanism of the superfine Ag NWs is proposed to explain the growth process of the Ag NWs with the introduction of KBr. The formation of Ag NWs probably involves the following chemical reactions:…”

Superfine silver nanowires (Ag NWs) with diameter of 40~50 nm and length of 5~10 µm have been synthesized by the self-seeding polyol reduction process using silver nitrate as the silver source, polyvinyl pyrrolidone (PVP) as the structural directing agent, ethylene glycol (EG) as the reducing agent and AgBr as the mediator. The influence of different factors on the growth of Ag NWs was studied. The morphology and crystalline phase of Ag NWs were characterized by the field emission scanning electron microscopy (SEM) and X-ray diffraction (XRD) respectively. The results indicate that the introduction of potassium bromide (KBr) is helpful for growth of Ag NWs with a high aspect ratio, as AgBr colloids formed in the initial stage and the dissociation reaction of AgBr colloids would largely influence the delivering rate of Ag+ ions, which controls the nucleation and growth of the Ag NWs. Finally, the possible growth mechanism of Ag NWs was discussed.

“…In the method, the aspect ratio of AgNWs depends strongly on kinds of inorganic salts, 24, 25 ratio of salt to silver nitrate, 26 molecular weight of PVP (polyvinylpyrrolidone), 27 ratio of PVP to silver nitrate, 25 reaction temperature, 26, 28 reaction time, 29 atmosphere, 30,31 and reagent-addition procedure. 23, 28, 32 Based on these parameters, many efforts have been exerted to control length and diameter of AgNWs to enhance performance on the application of transparent conductive electrodes.…”

Oxidation was a man issue for the silver-nanowire electrodes when the bulk silver reduces to nano-scale size, restricting it to practical application due to the significant rise of sheet resistance. We reported a simple method by virtue of incorporating polyethoxysiloxane (PES) into silver-nanowire layer to enhance the resistance to oxidation and thermal shock. As a result of the PES incorporation, the temperatures for oxidation to occur were raised from 250 and 300℃ to 300 and 500℃ under air and N 2 atmospheres, respectively. Moreover, after the PES incorporation the silver nanowires became tighter contact in cross connection due to the sol-gel shrinkage, resulting in a near 2-fold enhancement in the conductivity and superior bend performance compared to the pristine AgNWs electrodes. We used the silver-nanowire electrodes incorporated with PES to prepare the G/F/F-stack dual-touch sensor, revealing a rapid response and stable performances more than 3 months.

A template/electrochemical deposition method for fabricating silver nanorod arrays based on porous anodic alumina was presented. The barrier layer of porous anodic alumina templates was thinned by step-by-step voltage decrement method. Subsequently, silver ions were reduced into the channels of porous anodic alumina templates by electrochemical deposition method. Electrochemical impedance spectroscopy was utilized for analyzing the thickness of barrier layer of porous anodic alumina templates; the elementary composition and the size of silver nanorod arrays were characterized by X-ray diffraction and field-emission scanning electron microscope, respectively. Experimental results showed that the thickness of barrier layer of porous anodic alumina was suitable for alternating current electrochemical deposition, when anodizing potential was decreased to 70 V and widening time of porous anodic alumina in H 3 PO 4 solution is 80 min. And the silver particles could be deposited into the channels of porous anodic alumina templates at 11 V, 13 V, and 15 V. Different sizes of silver nanorod arrays were obtained by controlling the deposition time. The average diameter of silver nanorod is in the range from 346 nm to 351 nm which is almost consistent with the pore diameter of porous anodic alumina templates (367 nm). The uniform silver nanorod arrays have a considerable potential in the flexible and wearable electronic devices, optics, solar cell, the catalytical electrode, and so on.
