Research interests in the Soft and Hybrid Nanomaterials Lab lie at the interface of polymer and materials chemistry. Our group has focused on the development of innovative nanomaterials for energy and biomedical applications with the goals of understanding the fundamental physical and chemical principles of and providing new applications for complex macromolecular systems, including self-assembled polymers and carbon nanomaterials. The field of macromolecular systems is developing dynamically and presents new scientific and engineering challenges that must be addressed from a diverse expertise. Accordingly, my research group has combined multidisciplinary approaches, drawing on specialties from synthetic chemistry, polymer design and synthesis, nanomaterial preparation and characterization, and applications in energy and biomedical fields. Along with successful investigation of these topics, my research group now stands as an independent, innovative research program that comprises 8 Ph.D. students, 1 M.S. student, and 3 postdoctoral researchers. Our group has generated 60 original articles (including many in top-tier journals such as Nature Photonics, Nano Letters, ACS Nano, Energy & Environmental Science, Advanced Materials, Advanced Functional Materials, Advanced Energy Materials, Macromolecules, and Biomacromolecules), 2 reviews, and 9 registered patents and 8 filed patents.
Research Summary
Our research group is actively investigating the following topics: 1) synthesis of responsive polymers and exploration of their potentials in human health, and 2) synthesis of defective nanocarbons and exploration of their potentials in energy devices. These seemingly different, yet complementary, research topics integrate the existing knowledge of material synthesis and characterization and encompass the breadth of complex macromolecular systems from top-down to bottom-up approaches.

Environmentally-responsive polymers with superior biocompatibility

Layer-by-layer assembly
Versatile protocol for assembling macromolecular structures

Graphene oxide
Synthesis, assembly, and device applications

Carbon nanodot
Synthesis and optoelectronic/photocatalytic applications

고분자 및 탄소 소재 연구실에서는 기능성 고분자를 디자인하여 합성하고 이를 이용하여 생물학적 응용을 연구하며, 또한 탄소소재를 합성하여 이를 기반으로 에너지 소재로 응용하는 연구를 진행하고 있습니다. 이렇게 두가지 다르게 보이는 연구는 복잡성 거대분자의 이해를 높이기 위한 연구의 일환으로 활발하게 진행이 되고 있습니다.
