Research Progress of Conductive Ink and Its Printing Technology

This paper reviews the research progress of conductive inks and their printing methods, providing a reference for the development of inexpensive, stable performance, and excellent conductivity of the conductive ink. Through consulting literature, the preparation methods, printing methods and application fields of various conductive inks were summarized, the paper classified the conductive inks systematically, compared the performance, advantages and disadvantages of various conductive inks, and analyzed the printing technology, prospected the development prospect of conductive ink. At present, research on conductive inks is focused on low-temperature sintered inks with conductive fillers such as nano-silver, nano-copper, graphene, etc. The printing methods of conductive inks are mainly screen printing, inkjet printing, etc., which are mostly used to prepare sensors and flexible wearables. Future research still needs to focus on how to manufacture conductive inks at a low cost, low energy consumption, and simple mass production. Conductive inks will be combined with environmentally friendly printing methods to develop toward high conductivity and high printability, and become a key technology in the field of printed electronics.
