Copper nanoparticles improved in size and uniformity had been successfully prepared by modified polyol process using appropriate reducing agent. Obtained copper nanoparticles had no oxidation phase after 20 days without any ambient control and excellent dispersion stability in the stationary state without sedimentation. In this study, it was considered that the introducing of hot addition technique and the controlling of reducing agent-to-copper precursor mole ratio palyed an important role in determining the smaller and well-dispersed copper nanoparticles. The specific resistance was very low even at the low heating temperature. From the printability test, it can be concluded that the synthesized copper nanoparticles in this study can be considered as a very useful material for microscale patterning. |
