PAIR Seminar by Prof LENG Jinsong (冷勁松教授) on 15 July 2024

Topic: Shape Memory Polymer Composites: Programmability, 4D Printing and Applications
Speaker: Prof. LENG Jinsong (Harbin Institute of Technology, China)
• Dean of School of Future Technology
• Director of the Center for Smart Materials and Structures (CSMS)
• Director of International Center for Applied Mechanics
Abstract: Shape memory polymers and their composites are smart materials with excitation response. They have the ability to maintain temporary shape and return to their original shape under specific external environment excitation. At present, shape memory polymers such as epoxy, cyanate ester, styrene, polyimide, polylactic acid, and polyurethane with adjustable glass transition temperatures have been developed. Smart structures prepared based on shape memory materials have unique shape memory properties and characteristics of lightweight and high strength and have the functions of active deformation, self-sensing and self-repairing. We have developed a variety of shape memory smart structures, which have been initially applied in aerospace, biomedical, 4D printing, and other fields. These materials offer significant promise for future smart products in many areas of science and technology.
