Particle-free silver conductive ink is widely used in printed electronics industry because of its higher stability and lower post-processing temperature. According to the choice of silver precursors, the research progress of particle-free silver conductive inks with silver neodecanoate, silver citrate, silver oxalate, silver carbonate, silver acetate, silver nitrate and silver tartrate as precursors was reviewed. In addition, the selection and processing of the substrate when ink is used for inkjet printing, the microstructure structure control, the post-processing methods of ink printed patterns, the application of ink, and the prospects of particle-free silver conductive ink were introduced. |
