“…This was This was due to the etching between the MAX layer and the aluminum layer, embedding the surface active groups Tx(such as -OH, -F, and -O), thus increasing the layer spacing [ 34 ]. Furthermore, the presence of a diminishing peak (110) at 61.5° indicated that the crystallinity and degree of order of TiAlC 2 decreased as the reaction progressed [ 35 ]. The morphology of Max and MXene nanosheets was observed by scanning electron microscopy (SEM).…”

Flexible electronic devices and conductive materials can be used as wearable sensors to detect human motions. However, the existing hydrogels generally have problems of weak tensile capacity, insufficient durability, and being easy to freeze at low temperatures, which greatly affect their application in the field of wearable devices. In this paper, glycerol was partially replaced by water as the solvent, agar was thermally dissolved to initiate acrylamide polymerization, and MXene was used as a conductive filler and initiator promoter to form the double network MXene-PAM/Agar organic hydrogel. The presence of MXene makes the hydrogel produce more conductive paths and enforces the hydrogel’s higher conductivity (1.02 S·m−1). The mechanical properties of hydrogels were enhanced by the double network structure, and the hydrogel had high stretchability (1300%). In addition, the hydrogel-based wearable strain sensor exhibited good sensitivity over a wide strain range (GF = 2.99, 0–200% strain). The strain sensor based on MXene-PAM/Agar hydrogel was capable of real-time monitoring of human movement signals such as fingers, wrists, arms, etc. and could maintain good working conditions even in cold environments (−26 °C). Hence, we are of the opinion that delving into this hydrogel holds the potential to broaden the scope of utilizing conductive hydrogels as flexible and wearable strain sensors, especially in chilly environments.

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.

Three‐dimensional (3‐D) printing technology (3‐DPT) also referred to as additive manufacturing (AM) has advanced rapidly and is vastly used in varying manufacturing fields because of the minimization of waste materials and the ability to form complex geometrical shapes from micro‐ to macroscale. Nowadays, additive manufacturing (AM) has emerged extensively in varying engineering, architectural, medical, industrial, and manufacturing fields. Four‐dimensional (4‐D) printing technology (4‐DPT) synergizes 3‐DPT with stimuli‐sensitive materials and has garnered wide attention for smart additive fabrication. More so, 4‐DPT has displayed great prospects in numerous engineering applications including origami actuators, drug transport, robotics, smart clothing, and adaptive metamaterials. Hence, this elucidation presents recent advances in PLA additive manufacturing (3‐DPT) and applications. Insight into 4‐DPT is also presented.
