The wide application of flexible electronics in many fields such as production and life has made it a current research hotspot Electrohydrodynamic direct writing technology has become a promising meth

In summary, the proposed ink formulation based on the silver-amine complexation mechanism has great potential in the preparation of flexible electronics using electrohydrodynamic direct writing technology. Its low cost, high efficiency, and ability to prepare high-resolution patterns make it an attractive option for researchers in this field. The particle-free ink prepared by a one-pot method has the advantage of low-temperature sintering without metal particle agglomeration, which overcomes the common problems of traditional metal-based inks. Additionally, the self-stacking property of the prepared fiber allows for control of the resistance value of the fiber. These features make the ink formulation an excellent candidate for future research and development in the field of flexible electronics.
