“…In order to overcome the poor mechanical properties and stability of MXene, [25] highly flexible PVA was introduced into the MXene, [26] and the influence of changing PVA content on its structure and performance was explored (as shown in Figure S2, Supporting Information). As we expected, the microstructure of PMP films will possess a morphology similar to a "brickmortar" sandwich structure, with PCC, MXene, and PVA equivalent to the brick, sand, and cement in the construction of "brick-mortar" buildings (Figure 2a).…”

The rapid development of portable flexible electronic devices means a multifunctional composite film with excellent thermal management capability, high electromagnetic interference (EMI) shielding, and a strong fire safety performance is urgently required. In this paper, inspired by a "brick-mortar" sandwich structure, phase change capsules (PCCs) and MXene nanosheets are prepared. Subsequently, a one-step vacuum-assisted filtration method is used to fabricate a multifunctional flexible PCC/MXene/polyvinyl alcohol (PMP) phase change composite film with high light-to-thermal conversion efficiency, Joule heating generation, fire safety, and EMI shielding effects. The superior preparation technology endows the film with multi-source driven thermal management capabilities and excellent EMI shielding effectiveness values (43.13 dB). In addition, the PMP film exhibits good flexibility and high enthalpy (136.8 J g −1 ). Surprisingly, the PMP film's excellent fire safety properties improve its reliability and safety. In summary, the simple preparation technique and outstanding overall performance of the PMP films provide broad application prospects in advanced thermal management and EMI shielding in wearable products.

“…Due to the termination groups (–O, –OH, and/or –F), MXene nanoparticles are easily surface modified and grafted with chemically active groups, which can reduce the heavy accumulation of MXene flakes, increase the effective catalytic area, and improve their catalytic activity and stability [ 23 , 24 , 25 ]. In addition, MXene can play an excellent role in flame retardation with its layered barrier and metal ions to retard the combustion processes of polymers [ 26 ].…”

In this work, a novel functionalization strategy for ZIF-67-modified layered MXene was proposed, aiming at improving the fire safety of thermoplastic polyurethanes (TPU). The ZIF-67@MXene was verified by microscopic morphology, elemental composition, functional group species and crystal structure, and then the successfully prepared ZIF-67@MXene was introduced into the TPU material. When ZIF-67@MXene content was only 0.5 wt%, the peak heat release rate, total heat release rate, peak smoke release rate, total smoke release rate, and CO yield of the TPU/ZIF-67@MXene composites were reduced by 26%, 9%, 50%, and 22%, respectively, compared with the pure TPU. The thermogravimetric tests showed that the residual char of TPU/ZIF-67@MXene composites was the most in all samples. In short, the high-quality carbon layer of TPU/ZIF-67@MXene composites acts as a physical barrier to the transfer of heat and toxic gases, greatly improving the flame retardant properties of the TPU polymer.

“…6 MXene (Ti 3 C 2 T x ) is a novel two-dimensional nanosheet material, which has abundant functional groups (-F, QO, or -OH) on its surface. [7][8][9][10][11][12] Ti 3 C 2 T x is prepared via etching and peeling Ti 3 AlC 2 with hydrofluoric acid (HF), which has been extensively used in catalysis, energy storage and conversion, molecular separation, and other fields due to its outstanding thermal stability, electrical conductivity, mechanical strength and optical properties. 13,14 Recently, MXene has been confirmed as a potential flame retardant in polymeric materials, including but not limited to TPU, polyurethane foam, polyvinyl alcohol (PVA), polystyrene and polylactide for its excellent thermal stability and unique nanosheet structure, which can effectively enhance the thermal stability of polymers.…”
