“…Physical methods, like the ball-milling method, 24 can be used to prepare Ag nanoflakes, but the nanoflakes have poor crystallinity and a rough surface. Chemical methods, such as electrochemical methods, 25 ultrasonic radiation, 26 solvothermal methods, 27 direct chemical reduction, 28 and photo-induced chemical methods, 29 have been widely used to synthesize Ag nanoflakes. A solvothermal method has been used to fabricate Ag nanoplates by reducing AgNO 3 with N , N -dimethylformamide in the presence of PVP at a high temperature of 160 °C, 27 but the Ag nanoplates usually have a low aspect ratio.…”

“…Synthesis of Ag nanoplates (AgNPTs) will benefit optical bio‐sensor, cell performance and photo‐current density with enhanced power conversion efficiency, catalyst, surface‐enhanced resonance scattering (SERS) substrate, and antibacterial activities . However, in many synthesis either organic solvents like N , N ‐dimethylformamide or solvothermal processes involving organic solvents, high temperature, and long reaction time are needed. These synthesis of AgNPTs are either environmental unfriendly or energy consuming.…”

This work describes a strategy of assembling horizontally oriented Ag nanoplates (AgNPTs) with PSS-Ag as the precursor of silver by the layer-by-layer (LbL) technique on planar substrates. These AgNPTs have a lateral dimension of 20-80 nm and a thickness of 9-12 nm. A corresponding formation mechanism of these AgNPTs is discussed considering the orientation of the polyelectrolytes molecules, as well as their confinement effect on the diffusion of Ag nanoparticles. The exposed horizontal surfaces of the AgNPTs correspond to low free energy; they show an active antimicrobial activity. No Staphylococcus aureus colonies appear on the nutrient agar medium inoculated and incubated with S. aureus solutions treated by LbL films containing AgNPTs. The horizontally oriented AgNPTs by the described strategy in this work not only provides a novel method for controlled assembly of AgNPTs, but also provides insight in the antimicrobial behavior of nanoplate surfaces with low free energy.

In this paper, silver nanoplates of 100 to 500 nm size were synthesized by reduction of silver nitrate with N,Ndimethylformamide, using poly(vinylpyrolidone) as a surfactant and ferric chloride as a controlling agent, at 120 to 160°C for 5 to 24 hours. The influence of the concentration of ferric chloride, the reaction temperature and reaction time on the morphology of the product has been investigated by transmission electron microscopy, scanning electron microscopy and UV-Vis spectroscopy. The results indicated that the products obtained at the low reaction temperature and short reaction time in the presence of FeCl 3 in the reaction solution were in the form of silver nanoplates, whose morphology was mainly triangular and hexagonal. In addition, the size and thickness of the nanoplates increased with increasing of the FeCl 3 concentration. At a high reaction temperature and long reaction time, the truncated triangle and hexagonal nanoplates were mainly produced. Furthermore, the sintering behavior of nanoplates was studied and the results showed that sintering of the silver nanoplates started at 180°C, and a typical sintering behavior was observed at higher temperatures. The incorporation of the silver nanoplates into the polymer matrix with micro-sized silver flakes led to an increase in the matrix resistivity in almost all cases, especially at high fractions and low curing temperatures. The curing temperature had an influence on the resistivity of the conductive adhesives filled with micro-sized silver flakes and silver nanoplates due to sintering of the silver nanoplates.
