“…Therefore, potential alternative transparent conductive materials are being sought to substitute ITO. Several alternative materials have attracted considerable research interest, including carbon-based materials (graphene [5][6][7][8] and carbon nanotubes [9][10][11][12]), poly (3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) [13,14] in conductive polymers, and metal nanomaterials, such as silver nanowires [15][16][17] and copper nanowires [18][19][20]. Among these alternatives, the electrical conductivity and transmittance of carbon-based materials are inferior to silver nanowires [21].…”

Silver nanowires are receiving increasing attention as a kind of prospective transparent and conductive material. Here, we successfully synthesized high-performance silver nanowires with a significantly decreased reaction time by a modified polyol method. The synthesis process involved the addition of halides, including NaCl and NaBr, to control the release rate of Ag+ ions, as Cl− and Br− ions react with Ag+ ions to form AgCl and AgBr with different solubilities. As a result, Ag+ ions could be slowly released by graded dissolution, and the formation of silver nanowires was promoted. The results showed that the concentration of the added halides played an important role in the morphology of the final product. High-quality silver nanowires with an average diameter of 70 nm and average length of 21 μm were obtained by optimizing the reaction parameters. Afterwards, a simple silver nanowire coating was applied in order to fabricate the transparent conductive films. The film that was based on the silver nanowires provided a transmittance of 91.2% at the 550 nm light wavelength and a sheet resistance of about 78.5 Ω·sq−1, which is promising for applications in flexible and transparent optoelectronic devices.

“…It is indicated that the Ag NWs are preferentially formed at a higher NaCl concentration. Similarly, Trung et al [66] also found that Ag NWs became longer and thinner by increasing NaCl concentration, and Ag NPs are formed without NaCl. They also added 0.4 mM KBr in the solution and found that the diameter of Ag NWs further decreased to 20–50 nm and the length increased to 30–60 μm.…”

Flexible transparent conductive electrodes (TCEs) are widely applied in flexible electronic devices. Among these electrodes, silver (Ag) nanowires (NWs) have gained considerable interests due to their excellent electrical and optical performances. Ag NWs with a one-dimensional nanostructure have unique characteristics from those of bulk Ag. In past 10 years, researchers have proposed various synthesis methods of Ag NWs, such as ultraviolet irradiation, template method, polyol method, etc. These methods are discussed and summarized in this review, and we conclude that the advantages of the polyol method are the most obvious. This review also provides a more comprehensive description of the polyol method for the synthesis of Ag NWs, and the synthetic factors including AgNO3 concentration, addition of other metal salts and polyvinyl pyrrolidone are thoroughly elaborated. Furthermore, several problems in the fabrication of Ag NWs-based TCEs and related devices are reviewed. The prospects for applications of Ag NWs-based TCE in solar cells, electroluminescence, electrochromic devices, flexible energy storage equipment, thin-film heaters and stretchable devices are discussed and summarized in detail.

Metal‐based nanoentities, apart from being indispensable research tools, have found extensive use in the industrial and biomedical arena. Because their biological impacts are governed by factors such as size, shape, and composition, such issues must be taken into account when these materials are incorporated into multi‐component ensembles for clinical applications. The size and shape (rods, wires, sheets, tubes, and cages) of metallic nanostructures influence cell viability by virtue of their varied geometry and physicochemical interactions with mammalian cell membranes. The anisotropic properties of nonspherical metal‐based nanoarchitectures render them exciting candidates for biomedical applications. Here, the size‐, shape‐, and composition‐dependent properties of nonspherical metal‐based nanoarchitectures are reviewed in the context of their potential applications in cancer diagnostics and therapeutics, as well as, in regenerative medicine. Strategies for the synthesis of nonspherical metal‐based nanoarchitectures and their cytotoxicity and immunological profiles are also comprehensively appraised.
