摘要：One of the widely used methods for the synthesis of silver nanoparticles (Ag NPs) with good dispersion is chemical reduction method in the presence of polyvinylpyrrolidone (PVP). In this paper, we describe the synthesis Ag NPs using silver nitrate as a source of silver ions, PVP as a protective agent and glucose as reducing agent. In order to achieve the smallest average particle size, the influence of the mass ratio of PVP/AgNO3, glucose/AgNO3 and reaction temperature to the size distribution of Ag NPs was investigated. The smallest particle size (40nm) can be obtained by temperature 60°C, weight ratio of glucose to silver nitrate 2.5g/g and weight ratio of PVP to silver nitrate 1.6g/g. Synthesized AgNPs are characterized by scanning electron microscopy, X-ray diffraction, and UV-Vis spectroscopy. Results showed that the particle size of silver nanoparticles less than 100 nm with a narrow size distribution and high purity is prepared. These particles were used to prepare a conductive pattern applied on a glass plate and the patterns with resistivity as low as 3.1μΩcm can be obtained. The results revealed that PVP polymer plays an essential role in obtaining nanoparticles with a good specification.
