Topic: Application of Metamaterials Fabricated by Polymer Brushes

Speaker: Prof. Jem-kun Chen, Taiwan University of Science and Technology

Sponsor: School of Materials Science and Engineering

Abstract:

In this talk, we focus on the technology of polymer brush patterning. Grafting polymerization and characterizations of polymers including PS, PMMA, PNIPAAm and PDMAEMA are introduced firstly. These polymers are fabricated as one or two dimensional periodic relief grating to observe their stimuli-responsive change in color by naked eyes. In addition, metamaterials, such as grating or photonics, can be also applied to detect the specific biomacromolecules and VOC, which may be an important topic in the future.

Introduction to the Speaker:

Jem-kun Chen received his BS (1996) and MS (1998) in Chemical Engineering from National Tsing Hua University (Taiwan) and his PhD (2003) from lab of professor Feng-Chih Chang in Department of Applied Chemistry from National Chiao Tung University (Taiwan). From 2003 to 2004 he was a postdoctoral fellow with Professor Samukawa in the Department of Fluid Science at Touhoku University, Sendai (Japan), where he investigated the fabrication and analysis of quantum dots and nanodisks. In 2005 he joined the Department of Biomechatronics Engineering at Ping-tung University (Taiwan) as an Assistant Professor. Since 2006 he has been an Assistant Professor of Polymer Engineering at Taiwan University of Science and Technology. He was an Associate Professor of Materials Science and Engineering at Taiwan University of Science and Technology from 2009 to 2012. In 2013 he was promoted to Professor of Materials Science and Engineering at Taiwan University of Science and Technology. Dr. Chen’s current research emphasizes the processing, characterization, modeling, and optimization of polymer brush devices for optical and biological sensors. He has published over 80 articles (2004–2014).
