“…Rigid regions, composed of rigid segments, chain entanglements, crystalline phases, and crosslinking points, are involved in the structural stability and recovery of permanent shape. − Programable deformation ability allows SMPs to be widely used in fields, such as biomedical tissues, smart actuators, electronic devices, and aerospace structures, − which could be triggered by diverse external stimuli, including heat, light, electricity, magnetic field, and solvent . Nevertheless, SMPs, such as polylactic acid, − polyurethane, − and polycaprolactone, − with excellent self-deformation ability, usually exhibit the weak mechanical performances and poor thermal stability, which restrict their applications in engineering structures. Therefore, a SMP with both good mechanical properties and outstanding shape memory ability has attracted much attention and increasingly become the research hotspot.…”

Reversible dynamic bonds are able to crack and recombine upon external stimuli, which endow polymers with exceptional self-healing, reprocessing, and reversible deformation ability. In this paper, we integrated the metal coordination bonds into shape memory poly(aryl ether ketone) (PAEK) to fabricate smart materials with multifunctionalities. Through tuning the metal ion content and species, the enhancement of shape memory behaviors was achieved, including the high recovery ratio (over 98%) and fixity ratio (over 98%), which was closely related to the synergic effect of the intrinsic motion ability of PAEK matrix and the cracking-recombination of coordination bonds. Besides, through the combination of the components with different Cu 2+ contents, in addition to the components with Fe 2+ coordination bonds, we fabricated the gradient shape memory structures with controllable shape memory and recovery behaviors. The manipulation of gradient coordination bonds resulted in different shape recovery speeds and directions. Furthermore, due to the dynamic cracking-recombination of coordination bonds, the metal-coordinated PAEK material exhibited the great selfhealing and reprocessing performances, which were significant for largely extending its application range.

“…[189][190][191][192][193][194][195] Such features of SMPs make them promising candidates for 4D printing, and more recently, SMPs based on conductive nanofillers, endowing SMEs to the prepared nanocomposites, are frequently studied and discussed. [69,[196][197][198][199][200][201][202] Most commonly employed SMPs are polycaprolactone (PCL), polytetrafluoroethylene, polylactide, ethylene-vinyl acetate, polyurethanes, and (meth)acrylates.…”

3D printing is revolutionizing the manufacturing sector due to the myriad of materials and techniques available. Furthermore, it allows decentralized production sites for both industry and the public. However, it is restricted to static structures that cannot react to external stimuli or adapt to the environment and are, therefore, not suitable for functional and motile parts. Recently, two approaches are proposed to give dynamism to 3D printed structures: the printing of “stimulus‐responsive” (a.k.a. smart) materials and “4D printing,” the first implying features change due to a stimulus while the second indicating the time evolution of properties after a stimulus activation. Nanomaterials, particularly 2D nanomaterials, exhibit a broad and distinctive combination of features. Thus, they are highly effective at enabling this dynamism due to their morphological, optoelectrical, and mechanical properties. This review summarizes recent advances in 3D/4D printing of smart deformable and stimuli‐responsive materials which utilize 2D nanomaterials. The benefits of 2D materials in this framework are summarized, and how to translate their potential into 3D/4D printing is also discussed. The most promising achievements to date are deformable piezoresistive materials for strain sensing, Joule heaters, and actuators. Future advancements and possible upcoming application areas are finally proposed.

“…One of the most recent works in the scientific literature, focused on the development of a material with improved thermal and mechanical properties and with shape-memory properties, was reported in 2021 by Liu et al [98]. They prepared a composite film by electrospinning, constituted by perylene-bisimide-functionalized graphene nanosheet (PBI-GN) obtained via π-π stacking between PBI, graphene, and PLA.…”

This review aims to point out the importance of the synergic effects of two relevant and appealing polymeric issues: electrospun fibers and shape-memory properties. The attention is focused specifically on the design and processing of electrospun polymeric fibers with shape-memory capabilities and their potential application fields. It is shown that this field needs to be explored more from both scientific and industrial points of view; however, very promising results have been obtained up to now in the biomedical field and also as sensors and actuators and in electronics.
