Research Progress of Shape Memory Poly(aryl ether ketone)
Shape memory polymers have garnered considerable interest due to their distinctive stimulus-response and deformability,yet the physical and chemical properties of the commonly used shape-memory materials themselves have restricted the range of applications and hindered the realization of highly sophisticated applications in aerospace and other fields.As a specialized engineering plastic,poly(aryl ether ketone)(PAEK)possesses remarkable properties in terms of high and low temperature resistance,self-lubrication,mechanical strength,solvent resistance,and more.Consequently,it is essential to further explore PAEK with impressive shape memory capabilities.In this paper,we review the research progress of shape memory PAEK in recent years,with a focus on the influence of composite modification,chemical modification,and the combination with 4D printing technology on the shape memory performance of the PAEK.This paper,therefore,provides a reference for further development and application of shape memory smart materials.
