Practical Method to Synthesize Silver Nanoparticles for Electro-Conductive Inkjet Inks in Aqueous Medium

Abstract:

This paper describes a new method to prepare silver nanoparticles useful for printing electronic circuits. We have tried to develop a silver nitrate reduction method, with which a certain reducing agent has played an important role in the reduction of silver ions in an aqueous solution. The reduction has occurred rapidly at room temperature and the silver particles have been separated very easily from the solution in a short time. In this process, any organic solvent has not been used and separation of silver nanoparticles has not been complicated. All chemicals used in this study have been water-soluble. Small and relatively uniform particles of a diameter lower than 10 nm can be obtained with high purity and high yield. These can result in low cost, safe treatment and good for environment protection. This method of producing colloidal silver nanoparticles will find practical use in electronics applications.
