Presentation Summary

In our talk, we will introduce a flash light sintering technique for millisecond, large area sintering of cheap metal nanoinks in ambient conditions for printed electronics devices such as Flexible PCB.
Flash light sintering of various conductive metal nanoinks such as silver, copper, nickel and hybrid Cu-Ag nanoink will be introduced and their sintering mechanism will be discussed in-depth. Also, their applications to the variety of the industries will be introduced. It is expected that flash light sintering technology combined with the cheap metal nanoparticle inks technology would open new avenue in the field of printed electronics and energy harvesting/ storage applications.

Speaker Biography (Yong-Sul Song)

Dr. YongSul Song received his Ph.D. in Material Science & Engineering from Seoul National University, Seoul Korea in 1990. From that time, he is trying to develop the new kinds of electronic materials for IT and energy applications. Especially, he has devoted much effort to the development and industrialization of nano materials. Now, as a vice president/CTO, he is in charge of the Research Center for Advanced Materials in Amogreentech Co., Ltd. Amogreentech is interesting in the development and application of nano inks/pastes and nano membranes using nano particles and nano fibers for flexible and wearable devices.

Speaker Biography (Hak-Sung Kim)

Prof. Hak-Sung Kim received his Ph.D. in mechanical engineering from the Korea Advanced Institute of Science and Technology (KAIST) in 2006.
When he was in UCLA (2008) as the lecturer and postdoctoral researcher, he developed and published the journal paper about the intense pulsed light sintering of copper nanoparticles for printed electronics for the first time in the world (Applied Physics A, 97, 791-798, 2009). Since 2008, he has worked in the field on flash light sintering of the metal nanoinks for about 8 years, which will be our main topic in this joint presentation with Dr. YongSul Song. Prof. Kim is currently serving as an associate professor in Hanyang University.
