Thermally induced shape memory polymers (SMPs) are an important class of smart materials which can switch their shape in a predefined way to respond to an external stimulus1. There has been significant interest to develop SMPs for the last two decades, especially for the ones that can be triggered by body temperature due to their great potential for biomedical applications such as cardiovascular stents2, implants3, self-healing coatings4, actuators5 and tissue engineering6. Until now, researchers mainly focused on copolymers of poly(lactide)7, poly(glycolide)8 and poly(ɛ-caprolactone)3 and the polyurethane9 to obtain SMPs that can be triggered around the body temperature10. Each application requires a different combination of material properties and functions. Therefore, SMPs with different characteristics are required to fulfill the demands of various applications. Herein, we describe PSf and PVDF based amphiphilic graft copolymers with thermally activated shape memory behavior. Atom transfer radical backbones with non-linear derivatives of PEG to obtain shape memory graft copolymers via “grafting from” strategy. Copolymers exhibited excellent shape memory properties around Tm of the soft segments and full recovery was achieved within seconds. These soluble and processable SMPs could potentially play an important role in biomedical applications. 1.Pilate, F.; Toncheva, A.; Dubois, P.; Raquez, J.
