Minsu Kim is a research scientist in the Center for Advanced Functional Polymer at Korea Research Institute of Chemical Technology (KRICT). Prior to joining KRICT, he conducted research assistant at Nam’s research group in University of Illinois at Urbana-Champaign. He obtained his M.S. and B.S. degree in Material Sciences and Engineering in 2016 and 2017, respectively at University of Illinois at Urbana-Champaign. His research at the KRICT focuses on synthesis of advanced engineering polymers and CO2 laser based carbonization of polymeric materials to fabricate functional graphitic materials. His research aims to combine graphitic carbon materials and polymeric materials to create high performance materials with new functionalities in mechanical, optical, electronic properties. He explores various fields including Electrochemical sensing, Energy harvesting, Energy storage, and Optoelectronics.


3-dimensionally (3D) porous graphene from aromatic polymeric materials has been widely explored for various applications, due to its open porous structure, high electron mobility, physiochemical stability, and flexibility. In my talk, I will discuss how engineering of polymeric precursors allows for creating new physical, electrochemical, and photothermal functionalities in the 3D porous graphene. I will introduce three major approaches for engineering polymeric precursors, and resulting porous graphene with new functionalities. First, I will discuss how designing chemical functional groups in polymeric precursors enables to generate 3D porous graphene with high amounts of micropores (pore diameter < 2nm). I will also highlight highly microporous graphene with high specific active sites can be applied for high-performance microsupercapacitors. Second, I will discuss how solution-processible polymeric precursors enable to fabricate homogeneous films with metal-ligands, resulting in hybrid nanoassembly of 3D porous graphene and metal nanoparticles. I will also discuss the nanoassembly enables high electrochemical properties and can be applied for high performance hydrogen detection systems. Lastly, I will discuss, how polymeric precursors with porous structures enable to fabricate bilayer membranes of 3D graphene and polymers for solar steam generation.
