제목 Effect of Counter Ion of Silver Salt on the Preparation of Highly Concentrated Silver Colloids through Polyol Process
초록  Silver nanoparticle has been widely used in many fields including electronic and medical industries. Various techniques such as wire explosion, electrochemical synthesis, and polyol process have been developed to prepare silver nanoparticle. Among them, polyol process is appropriate to control size and shape of silver particle. In this study, highly concentrated silver colloids were prepared through reduction of Ag+ ions by using di-ol solvents and polyvinylpyrrolidone (PVP) as a stabilizing agent. Also, the influence of counter ion on the formation of silver colloids was investigated by using different Ag salts such as AgNO3, AgBF4, and so on. All properties of silver colloids were analyzed by using DLS, TEM, and UV-vis spectrophotometer.
