| In this work, silver nanoparticles with the size in the range of 30 nm to50 nm were prepared by chemical reduction method using silver nitrate, adipic dihydrazide and dextrose as the main raw materials. Nano-silver conductive inks were prepared by dispersing nano-silver particles in a specific proportion mixed solvent. Secondly, the nano-silver conductive ink was patterned by inkjet printing, and the morphology and conductivity of the nano-silver were studied. The effects of sintering temperature and sintering time on the resistivity of the inkjet printed electrodes were studied. The results showed that lower resistivity, the value was 0.34 mΩ.cm, could be obtained with sintering temperature raised up to 200℃, and the sintering time kept for 40 min. |
