YU School of Chemical Engineering Professor Kim Se-hyun’s research team (major in polymers and bio materials) developed the crystal-type electronic materials direct printing technology that can be applied to flexible electronic devices.
Crystallization and pattern-forming technologies for electronic materials in the past had multiple and complex procedures. The real-time direct printing technology that Professor Kim’s research team developed is a very simple technology that can control the crystallization orientation and patterns of electronic materials at low costs.

The printing technology of ink-jet printers commonly used today discharge ink through external pressure. Compared to this, the technology developed by Professor Kim’s research team applies an electric field between the nozzle and substrate to improve the crystal orientation of electronic material molecules, while forming patterns through the movement of the nozzle.

Professor Kim who led this research explained, “Because the crystallization direction and formation process are determined through the electric field and nozzle direction, very simple and large-area crystallization control is possible.” He added, “The technology developed here is expected to be applied in various flexible electronic devices. In addition to the transistor shown in this study, the technology was applied in smart window displays for which colors change depending on the electric field, and bio sensors as well, and we are planning to expand the fields of application through follow-up research.”
The research results were published in the latest issue of the world-acclaimed academic journal in physical chemistry, <Journal of Physical Chemistry Letters> (impact factor (IF) 9.353). This research was joined by Bae Jae-hyun (YU Graduate School of Advanced Organic Materials Engineering master’s degree graduate, current senior researcher at LG Display) as the first author and Professor Kim Se-hyun as the corresponding author.
