About

Dong Ki Yoon is a leading researcher in stimuli-responsive soft materials, specializing in shape memory polymers, liquid crystalline polymer networks (LCNs), and liquid crystalline elastomers (LCEs). His work focuses on designing materials that undergo precise structural deformation in response to external triggers such as light, heat, and electric fields—enabling applications in soft robotics, injectable medical devices, and advanced electronics. A major contribution is the development of light-driven shape memory thermoplastic polyurethane (TPU) by grafting azido TPU with photoswitchable azo compounds, achieving remote, programmable actuation. His recent research on dual stimuli-responsive MXene/polymer composites demonstrates multimodal actuation with enhanced motion control and environmental sensing capabilities. Yoon has also provided a comprehensive framework for actuation mechanisms in LCNs and LCEs, spanning from nanometer-scale precision to macroscale functionality. His highly cited works—including papers with 14 and 7 citations—underscore his impact on the field. Through these innovations, Yoon is advancing the next generation of intelligent, responsive materials for cutting-edge technologies.
