Ag nanoparticles synthesis method suffers from low concentration and the limitation particle sizes issues. We report an inexpensive, and reproducible method in highly concentrated water phase (＞0.1M). Ag nanoparticles were prepared by TA (Tannic acid) reduction in AgNO3 Aqueous Solutions. The addition of surfactant (Tween, Brij) easily reach the desirable particle size & high concentration. We were able to synthesize of as much as 10g of nanoparticles in the 10~20nm size ranges using simple wet process. The particles are stable in dried form and they can be redispersed in Aqueous Solutions. (25~50 wt%) and We printed them on various substrate. (Poly imide, Glass, Wafer, Photo Paper) Printed silver patterns were cured in the temperature range between 100 and 250 oC and showed low specific resistance (80 μΩ•cm). |
