  Abstract

In this study, silver particles were prepared using two polyols at different reduction rates under controlled experimental conditions. Isosorbide was employed as a novel polyol reductant for silver particles, and its reduction rate in the polyol process was compared with ethylene glycol (EG). When the isosorbide reductant was used in the polyol process, silver particles could be formed. However, the reduction rate of isosorbide was slower than that of EG, and the resultant silver particles thus had anisotropic shapes. Additionally, the size of silver particles was dependent on the presence and amount of the PVP stabilizer. Therefore, the shape and size of silver particles were mainly affected by the reduction rate and stabilizer, respectively.
