In the past few days, 2012-grade graduate student Liu Li from our department has published his research paper titled Anions-Mediated Synthesis of Monodisperse Silver Nanoparticles and Useful for Screen Printing of High-Conductivity on Patterns on Flexible Substrates for Printed Electronics in the Royal Society of Chemistry journal RSC Advances (SCI retrieval Source Journals, IF = 3.8).

The study focuses on the regulation of anions over the micromorphology of synthetic silver particles and the influence of silver nanoparticles with different morphologies on its electrical properties after printing. According to the research findings, silver nanoparticles synthesized with carbonate ions have a high electrical conductivity, up to 5.72 μΩ • cm, close to the conductivity of fine silver block material. This conductive ink can be printed on PET and paper, and can be further applied to electronics flexible printing.

The paper was funded by Natural Science Foundation of China and directed by Professor Wan Xiaoxia and Associate Researcher Wu Wei of our Department.
