Silver nanoplates, also referred to as nanoprisms or nanodisks, are two-dimensional plasmonic nanostructures that have attracted intensive attention due to their strong shape-dependent optical properties and related applications. In order to obtain the silver nanoplates with high concentration, the liquid-phase reduction method was adopted. Silver nanoparticles colloid was obtained by reducing the high molar concentration of AgNO3 (up to 3.17 M) with the hydrazine hydrate (H4N2 • H2O) as reductant in the presence of polyethylene pyrrole (PVP) as the protectant. 0.5 M Sodium Citrate is introduced into the precursor aqueous which containing AgNO3 and PVP, the molar ratio of PVP to AgNO3 was tuned from 0.64 to 1.5. When molar is 1.5, the mainly particles are silver nanospheres, on the contrary, the nanospheres are transferred into nanoplates as the ratio decreased gradually, until the mainly product are nanoplates. The constituent of the silver nano-clusters was established by performing the Powder X-ray diffraction. The nano-silver dispersion with average diameter is about 113.2 nm were finally deserved. The size distribution of the silver nanoparticles is recorded by the Zeta potential analyzer. Scanning electron microscope (SEM) was used to characterize the morphology of the nano-silver particles. The silver content is about 3%. Nano-silver colloid is obtained and purified by centrifugation and wash with deionized water and ethanol. Then, water-based silver conductive ink is obtained by adding some amount deionized water and additives and adjusted parameters, which could be widely used in printed electronics.

The Impact

It has many advantages with liquid phase reduction method to prepare the nano-silver, such as experimental conditions are simple, low cost, energy-saving, etc.. At the same time, the nano silver powder prepared by this method has high surface activity, catalytic property and wide usage. In this paper, nano-silver powder was prepared by changing the amount of protective agents with chemical liquid phase reduction method. This paper focuses on the impact of the amount of protective agent on the nano-silver. In addition, we also analyzed the reaction temperature, PH value of solution, viscosity and electrical conductivity on the preparation of nano-silver. Finally, test results from the TEM shows that the nano-silver was prepared with smaller size, uniform size and good dispersion.

Silver nanoparticles (AgNPs) were synthesizd by a light-assisted liquid phase reduction method with sodium hypophosphite as a reducing agent. DTAB was used to perform as the surfactant. AgNPs were characterized with powder X-ray diffraction (XRD) and scanning electron microscope (SEM). The result showed that the nanoparticles are spherical and cube. The effect of temperature on the morphology and properties of silver nanoparticles was investigated. The ultraviolet-visible (UV-vis) absorption and the fluorescent properties of the as-prepared AgNPs were explored.
