Research Interests: Shape Memory Polymer, 4D Printing

Summary
Shape Memory Polymers (SMPs) are a remarkable class of stimuli-responsive materials capable of programmable shape changes, positioning them at the forefront of smart material innovation.
Their transformative potential spans biomedical devices, soft robotics, 4D printing, and adaptive systems.
This Special Issue aims to showcase cutting-edge research and reviews addressing key challenges—such as enhancing mechanical properties, enabling complex shape transitions, and refining actuation mechanisms—while fostering interdisciplinary collaboration among chemists, materials scientists, and engineers.
Topics of interest include novel SMP design and synthesis, 4D printing, mechanistic studies and modeling, multifunctional SMPs, and emerging applications in biomedicine, soft actuators, and aerospace. We welcome original contributions that push the boundaries of SMP science and technology.
