外文摘要：Shape memory polymers(SMPs)and their composites(SMPCs)are smart materials that can be stably deformed and then return to their original shape under external stimulation,thus having a memory of their shape.Three-dimensional(3D)printing is an advanced technology for fabricating products using a digital software tool.Four-dimensional(4D)printing is a new generation of additive manufacturing technology that combines shape memory materials and 3D printing technology.Currently,4D-printed SMPs and SMPCs are gaining considerable research attention and are finding use in various fields,including biomedical science.This review introduces SMPs,SMPCs,and 4D printing technologies,highlighting several special 4D-printed structures.It summarizes the recent research progress of 4D-printed SMPs and SMPCs in various fields,with particular emphasis on biomedical applications.Additionally,it presents an overview of the challenges and development prospects of 4D-printed SMPs and SMPCs and provides a preliminary discussion and useful reference for the research and application of 4D-printed SMPs and SMPCs.
