“…Linear PEG was immobilized in a crosslinked poly (methyl methacrylate) [PMMA] network, forming a PMMA/PEG semi-IPN [174]. The incorporation of PEG in the network not only introduced an additional T trans (T m of PEG) but also broadened the T g of PMMA, resulting in a quintuple-SME.…”

Shape memory polymers (SMPs), as a class of programmable stimuliresponsive shape changing polymers, are attracting increasing attention from the standpoint of both fundamental research and technological innovations. Following a brief introduction of the conventional shape memory effect (SME), progress in new shape memory enabling mechanisms and triggering methods, variations of in shape memory forms (shape memory surfaces, hydrogels, and microparticles), new shape memory behavior (multi-SME and two-way-SME), and novel fabrication methods are reviewed. Progress in thermomechanical modeling of SMPs is also presented.

Abstract:This review paper summarizes the recent research progress in the underlying mechanisms behind the shape memory effect (SME) and some newly discovered shape memory phenomena in polymeric materials. It is revealed that most polymeric materials, if not all, intrinsically have the thermo/chemo-responsive SME. It is demonstrated that a good understanding of the fundamentals behind various types of shape memory phenomena in polymeric materials is not only useful in design/synthesis of new polymeric shape memory materials (SMMs) with tailored performance, but also helpful in optimization of the existing ones, and thus remarkably widens the application field of polymeric SMMs.

In this work, a bio-shape memory polymer (SMP) with high performance is prepared by using cellulose acetate (CA) as raw material. The materials exhibit good mechanical properties with tensile strength and elongation at break over 46 MPa and 115%, respectively. With hydrogen bond interaction as physically cross-linked points, the materials also present excellent dualshape memory properties with shape fixation and shape recovery ratio of about 99% and 96%, respectively. Moreover, the materials show good triple-shape memory effect. The recyclability of the materials is also investigated and the results show that the reclaimed samples still hold high mechanical and shape memory properties. With the intrinsic biocompatibility and biodegradation of CA, the materials could be an attractive candidate for applications in smart biomedical devices. Furthermore, the usage of CA as SMP could expand the view of preparing bio-SMP in future.
