One pot rapid synthesis of silver nanowires using NaCl assisted glycerol mediated polyol process

Abstract

We report, one pot rapid synthesis of silver nanostructures from AgNO3 through glycerol mediated polyol process with the assistance of polyvinyl pyrrolidone (PVP) and NaCl. The growth of silver nanostructures was studied by monitoring changes in the position of localized surface plasmon resonance band using the UV-vis-NIR spectroscopy. Morphology of the silver nanostructures was indentified using the scanning electron microscope which confirms the formation of nanoparticle, V-shaped and linear silver nanowires. The favorable temperature and NaCl concentration to obtain nanoparticles, V-shaped and linear silver nanowires are optimized. 5 mM NaCl at 250°C produced 55 -65 nm width, 4 µm long silver nanowires along [100] in PVP added glycerol medium within 25 minutes.

Enhancement of Mechanical Stability and Ionic Conductivity of Chitosan‐based Solid Polymer Electrolytes Using Silver Nanowires as Fillers

“…In addition, such fillers must be dispersed in a glycerol solvent, because the glycerol solvent was used as a plasticizer in the above experiment (Figure ). In order to prepare the solutions containing fillers with different shapes under the same experimental environments in a glycerol solvent, we refer to the reference, that introduce synthetic procedures for the synthesis of silver nanospheres and nanowires in a glycerol solvent. According to that reference, the formation of silver nanospheres and nanowires is determined by the presence of sodium chloride (NaCl).…”

“…In order to synthesize silver nanowires in a glycerol, we referred to the method reported by Shobin and Manivannan as depicted by red arrows in Scheme (a) . Poly(vinyl pyrrolidone) (PVP) (approximately 1.6%, w/w) and sodium chloride (NaCl) (5 mM) solution was prepared by dissolving 1 g of PVP (Ave. MW 40000, Sigma‐Aldrich, Munich, Germany) and 14.6 mg of NaCl (99.5%, OCI Ltd., Seoul, Korea) into 50 mL of glycerol (99.5%, Daejung Chemicals & Metals Co., Ltd., Gyeonggi‐do, Korea) with stirring for 3–4 h at 60 °C.…”

“…In this reaction, NaCl plays an important role for the synthesis of nanowires. Without NaCl, spherical silver nanoparticles (silver nanospheres) are produced instead of nanowires . Therefore, to facilitate the synthesis of silver nanospheres, NaCl was not added while the chemical reaction was carried out, but was added into the final solution to make the experimental conditions equivalent ((a)‐2) as depicted by blue arrows in Scheme (a).…”

Komposit Polianilina/Kitosan/Perak Nanowires Sebagai Elektrokatalis Reaksi Evolusi Hidrogen dalam Medium Netral

“…Mekanisme pembentukan AgNWs diawali oleh reaksi antara ion Ag + dengan ion Clmembentuk larutan koloidal putih AgCl, kemudian terjadi aglomerasi dengan bantuan PVP sebagai template sekaligus pereduksi melalui mekanisme reaksi redoks dengan pembentukan spesi radikal dari PVP disertai pelepasan atom H (Zhang et al, 2013). Proses reduksi AgCl menjadi Ag diikuti proses pertumbuhan kristal nanowires (Shobin and Manivannan, 2014 (Vetter, 1967).…”

Investigation on functionalization of cotton and viscose fabrics with AgNWs

“…PVP is an amorphous polymer, which is highly soluble in polar solvents, that directs the growth of nanowires and protects them from agglomeration Mohd et al 2014;Shobin and Manivannan 2014;Sun et al 2002). Briefly, 10 ml of 0.45 M EG solution of PVP (M w = 55 000) with 7 mg of sodium chloride (NaCl, CHEMPUR) was prepared and heated to 170°C.…”
