英文摘要:

      The work aims to study the nano-silver conductive ink and its application in flexible printing electronics. The research progress in recent years was expounded by summarizing the Chinese and foreign literature from the preparation of silver nanoparticles and conductive inks, the printing and sintering process, and the applications in flexible printing electronics technology. In the preparation and use of ink, simplifying the preparation process, reducing the production cost, achieving environmental friendly and low temperature sintering, and improving the substrate adaptability of ink are the focuses of future improvement of nano-silver conductive ink. Direct writing technology has the advantages of high precision and fast speed, and is gradually replacing screen printing technology to become the mainstream. The research focus of sintering process is to achieve low temperature sintering, in which chemical sintering process is simple, but improving the conductivity is the research difficulty, while other sintering methods have the disadvantages of expensive equipment and high environmental requirements. As a functional electronic material, nano-silver conductive ink is widely used in flexible printing electronics because of its excellent electrical properties and printability. In recent years, through the in-depth research and technical improvement of nano-silver and its conductive ink, certain progress has been made in the preparation of nano-silver particles, low temperature sintering technology and energy saving. At the same time, it is used as a functional material to print flexible sensors, RFID tag antennas, flexible electrodes, supercapacitors and solar cells, which is being widely studied and applied.
