“…[25] d-Ti 3 C 2 T x mainly displays two characteristic absorption bands at 3434 and 1626 cm −1 , corresponding to the vibration absorption of OH and CO. [26] In addition, T/A-5 composite fiber still shows mainly characteristic absorption bands of d-Ti 3 C 2 T x and ANF components and no new absorption bands are observed, suggesting that no chemical change occurs during the fibering process (Figure 2g). But basis on the careful analysis between partially enlarging 1700-1600 cm −1 , a shift of the CO group is observed, suggesting the chemical environment of CO group has undergone a certain change and the intermolecular H-bonds are formed.…”

“…But basis on the careful analysis between partially enlarging 1700-1600 cm −1 , a shift of the CO group is observed, suggesting the chemical environment of CO group has undergone a certain change and the intermolecular H-bonds are formed. [25,26] Because there are rich hydroxyl groups on the surface of d-Ti 3 C 2 T x , so d-Ti 3 C 2 T x are an ideal proton donor, while ANF is an ideal proton acceptor due to its abundant carbonyl groups. Therefore, H-bonds between OH groups for d-Ti 3 C 2 T x and CO groups for ANF are formed.…”

Full-temperature all-solid-state flexible symmetrical fiber supercapacitors (FSCs) are assembled by using montmorillonite flake/polyvinyl alcohol organic hydrogel (F-MMT/PVA OHGE) as the electrolyte and separator and Ti 3 C 2 T x /ANF-5% (T/A-5) fiber as the electrode, in which T/A-5 fiber is prepared by using delaminated Ti 3 C 2 T x nanosheets as assembled units and 5% of aramid nanofiber (ANF) as the functional additive using a wet spinning method in a coagulated bath with 0.5 m FeCl 2 solution. The T/A-5 hybrid fiber exhibits a specific capacity of 807 F cm −3 in 3 m H 2 SO 4 electrolyte, a superior mechanical strength of 104 MPa, and a high conductivity of 1025 S cm −1 . The assembled F-MMT/PVA OHGE T/A-5 FSC not only shows a specific capacitance of 295 F cm −3 and a capacitance retention of 91% at a current density of 5 A cm −3 after 10 000 charging/discharging cycles, but also a maximum volumetric energy density of 26.2 mWh cm −3 . Meanwhile, the assembled device displays good flexibility and excellent capacitance in a wide temperature range of −40 to 80 °C, the electrochemical performance of the FSC is maintained under varying degrees of bending. This study provides an effective strategy for designing and assembling of full-temperature all-solid-state symmetrical flexible FSCs with the optimal balance of capacitive performance and flexibility.

“…It is interesting that although the amount of MXene is consistent, the absorption performance exhibit obvious deviation between PUS‐MXene sample and PET‐MXene film. On account of the transparency to THz waves of both PET and PUS, [ 38,52,53 ] this phenomenon is probably owing to the special polyporous structure of PU sponge, resulting in internal multiple reflections that lead to a much higher THz absorption effectiveness.…”

Flexible and lightweight terahertz (THz) absorbers with high absorption performance are urgently indispensable in the application of foreign substance examination, molecular identification and 6G communication. Herein, cost‐effective approaches of autocatalytic plating and dip‐coating with a series of surface grafting are proposed to construct nickel/Ti3C2Tx (Ni/MXene) decorated polyurethane sponge (PUS) composite. The resultant PUS‐Ni/MXene sample exhibits average THz absorption shielding effectiveness (SEA) and absorption proportion of 42.7 dB and 99.9% from 0.1 to 2.2 THz at a thickness of only 1 mm. The THz SEA can achieve 69.8 dB for PUS‐Ni/MXene sample with 8 mm thickness while the specific SE is over 65.8 (dB cm3 g−1), surpassing most absorbers. To better understand the propagation characteristics of THz waves, the electromagnetic interference SEs and electric field distributions are calculated through finite difference time domain simulation, and verified by experiments. Moreover, the foldable and electrical properties endow the PUS‐Ni/MXene composite with smart pressure sensitivity that is promising for strain monitoring. The optimized PUS‐Ni/MXene sensor exhibits high sensitivity under a relatively small strain. And the outstanding long‐term stability and durability are also proved by 1200 stretching–releasing cycles. The as‐prepared THz absorber with excellent pressure sensing performance demonstrates enormous potential in future military and civilian applications.

Silver nanowire (AgNW) conductive film fabricated by solution processing was investigated as an alternative to indium tin oxide (ITO) in flexible transparent electrodes. In this paper, we studied a facile and effective method by electrodepositing Al2O3 on the surface of AgNWs. As a result, flexible transparent electrodes with improved stability could be obtained by electrodepositing Al2O3. It was found that, as the annealing temperature rises, the Al2O3 coating layer can be transformed from Al2O3·H2O into a denser amorphous state at 150 °C. By studying the increase of electrodeposition temperature, it was observed that the transmittance of the AgNW–Al2O3 composite films first rose to the maximum at 70 °C and then decreased. With the increase of the electrodeposition time, the figure of merit (FoM) of the composite films increased and reached the maximum when the time was 40 s. Through optimizing the experimental parameters, a high-stability AgNW flexible transparent electrode using polyimide (PI) as a substrate was prepared without sacrificing optical and electrical performance by electrodepositing at −1.1 V and 70 °C for 40 s with 0.1 mol/L Al(NO3)3 as the electrolyte, which can withstand a high temperature of 250 °C or 250,000 bending cycles with a bending radius of 4 mm.
