“…This feature makes them highly sensitive to water molecules, which is key to their water-induced shape-memory properties. The transformation of water-induced shape-memory materials results from the hydrogen-bonding interactions between water molecules and hydrophilic groups, and the water molecules that enter the polymer chain can act as a plasticizer to reduce the transition temperature and enable shape recovery. , To analyze the water resistance and absorption properties of the composite film, the swelling rate was first studied. As shown in Figure S9, the swelling rate of the composite film tends to decrease as the MXene content increases.…”

Recent advancements in artificial intelligence have propelled the development of shape-memory polymers (SMPs) with sophisticated, environment-sensitive capabilities. Despite the progress, most of the existing SMPs are limited to responding to a single stimulus and show poor functionality, which has severely hindered their future applications. Herein, we report a highperformance multistimuli-responsive shape-memory and selfhealing composite film fabricated by embedding MXene nanosheets into a conventional shape-memory sodium carboxymethyl cellulose (CMC) and poly(vinyl alcohol) (PVA) matrix. The incorporation of photothermal MXene nanosheets not only enhances the composite films' mechanical strength but also provides efficient solar−thermal conversion and robust light-actuated shape-memory properties. The resultant composite films exhibit an exceptional shape-memory response to various stimuli including heat, light, and water. Meanwhile, the interfacial interactions can be modulated by adjusting the MXene content, thereby enabling precise manipulation of the shape-memory performance. Moreover, thanks to the intrinsic hydrophilicity of the components and the unique physically cross-linked network, the composite films also demonstrate an effective water-assisted self-healing capability with an impressive healing efficiency of 85.7%. This work offers insights into the development of multifunctional, multistimuli-responsive shape-memory composites, opening up new possibilities for future applications in smart technologies.

As a result of nanotechnological advancement, parameters inducing flaws in shape memory polymers (SMP), such as weak mechanical properties, low electrical, and thermal conductivities, and so on, were mitigated through the inclusion of a versatile range of nanomaterials such as montmorillonites, carbon nanotubes, graphene and derivatives, cellulose nanocrystals, carbon nanofibers, and so on, thereby forming shape memory polymeric nanoarchitectures (SMPNs). Hence, this work elucidates most recently emerging advancements on multifunctional SMPNs filled by differing nanoparticulates. Varying multifunctional SMPNs exhibit responsivity to varying forms of stimulation strategies, including thermal responsivity, electroactivated, alternating magnetic field responsivity, light sensitivity, and water induced SMPs. Therefore, this article presents very recently emerging advancements in the construction, characterization, properties, and multifunctional applications of stimuliresponsive SMPNs, with special emphasis on functional and stimuli-responsive SMPNs. Furthermore, important functions of SMPNs such as stimuli-memory effect and self-mending abilities, as well as prospective strategies for future progress of these materials are highlighted.

Due to the advent of nanotechnology, deficiencies and limitations inherent in stimuli-responsive shape memory polymeric matrices (SMP), have been effectively mitigated, through the inclusion of a versatile range of organic or inorganic nanoparticulates within the confines of SMP matrice/s. This phenomenon has resulted in the emergence of shape-memory polymeric nanoarchitectures (SMPNs) possessing enhanced and outstanding properties, when compared with the pristine SMP, and this has subsequently enlarged their scope of applications (civil engineering, biomedical gadgets, aerospace, bionics engineering, energy, electronic engineering, household products, and textile engineering). Furthermore, SMPNs enhances athermal stimuli-activities including electroactivity, magneto-activity, water-activity, and photo-activity, as well as shape memory effect (SME) including multiple-shape memory effect (MSME), spatial shape memory effect (SSME), as well as dual-route shape memory effect (DRSME). This elucidation is essential and imperative at this time to enlighten the polymeric universe on new advancements in fabrication, features and applications of stimuli responsive SMPNs. Therefore, this paper, presents, very recently emerging advancements, in construction, characterization, properties and multifunctional applications of stimuli-responsive SMPNs with special emphasis on carbon nanotubes (CNT), carbon nanofibers (CNF), cellulose nanocrystals, and nanoclay reinforced SMPNs.
