Polymer Ionic Materials Laboratory
Welcome to the Hyeong Jun Kim research group at Sogang University
Charged macromolecules are everywhere! From biological macromolecules to synthetic polyelectrolytes for today's leading technologies, charged macromolecules are fundamental elements of our life.
Our team is engaged in exploring the physicochemical and biological phenomena of charged macromolecules as well as their applications in new functional devices. Our research aims to expand our understanding of charged macromolecules and translate their activities into soft and highly deformable functional devices.
The major topics that we are under active investigation are the following:
Design and synthesis of polyelectrolytes
Physicochemical properties and phase behavior of polyelectrolytes (complex coacervation)
Soft and highly deformable ionotronic devices and electro-adhesion of charged macromolecules
Electro-Chemical Depolymerization
Join our team!!
We are looking for highly motivated team members who like to share our vision on charged macromolecular research. Our team pursues highly interdisciplinary research, bridging chemical engineering, polymer chemistry and physics, electronic, robotics and mechanics.
