Institute of Nuclear Energy Research (INER) is a R&D Department major for Nuclear. INER has developed a lot of advanced technologies which have been adopted by many products in the market.
Conductive ink is one of the technologies that can improve the performance for electronics industry.
Conductive ink using copper nanoparticles has attracted much attention in printed electronics industry because of its low cost and high electrical conductivity. However, the problem of easy oxidation under heat and humidity conditions for copper material limits wider applications. In this project, we develop antioxidative copper inks. Importantly, these highly copper conductive films can be placed in an atmospheric environment for more than six months without the oxidation phenomenon. These unique features of our antioxidative copper conductive ink are particularly useful to many printed electronics applications such as flexible display systems, sensors, photovoltaic cells, and radio frequency identification.
