Research Status and Prospects of Particle-Free Silver Conductive Ink

Abstract

Abstract. Conductive inks are mainly used in the printed electronics industry. Particlefree conductive inks are prepared from organometallic compounds or complexes as precursors. They have the characteristics of preventing agglomeration and settling, not easily clogging the nozzles, and having a low heat treatment temperature, suitable for inkjet printing. Starting from precursors, the development statuses of conductive inks using silver acetate, silver citrate, silver neodecanoate, silver oxalate, silver tartrate, silver nitrate, and silver oxide as precursors were respectively introduced, summarized the main problems that existed, and put forward the outlook.

Low-Temperature Sintering of Ag Composite Pastes with Different Metal Organic Decomposition Additions

“…The thermal behaviors of seven MODs containing different amines were studied using simultaneous thermal analysis. It can be seen in Figure 4 h that the endothermic peak of silver oxalate (~240 °C) was significantly higher than the peaks exhibited by the MODs [ 20 ], which had endothermic peaks below 150 °C. Furthermore, a sharp loss in mass was observed during these peak temperatures, suggesting that the MODs have low decomposition temperatures.…”

“…The field of smart materials is rapidly developing, with some materials exhibiting the ability to produce nanoparticles at low temperatures [ 17 ]. Ag-based MOD (metal organic decomposition) is one such flexible electronic material that produces Ag nanoparticles upon exposure to light or heat (100–200 °C) [ 18 , 19 , 20 , 21 , 22 ]. MOD ink is typically prepared using silver salts (as precursors), organic amines (as complexing agents), and solvents and reducing agents, such as alcohols and organic acids.…”
