About

Ki Bong Lee is a leading researcher in the field of advanced polymer materials, with a primary focus on shape memory polymers, vitrimers, and additive manufacturing. His work centers on developing intelligent, responsive materials that combine the structural integrity of thermosets with the reprocessability of thermoplastics. Dr. Lee’s major contribution lies in the controlled formulation of epoxy vitrimers, enabling them to be both weldable and reprocessable—a critical advancement for sustainable manufacturing. His landmark 2021 paper on “Weldable and Reprocessable Shape Memory Epoxy Vitrimer Enabled by Controlled Formulation for Extrusion‐Based 4D Printing Applications” has garnered 23 citations, highlighting its impact on the emerging field of 4D printing. This work demonstrates how precise chemical design can unlock new functionalities in cross-linked polymer networks, allowing materials to change shape over time in response to external stimuli. By bridging the gap between fundamental polymer chemistry and practical 3D/4D printing technologies, Dr. Lee is paving the way for next-generation smart materials with applications in aerospace, biomedical devices, and adaptive structures.
