“…Finally, after removing the solvent phase, a porous structure is obtained. 196 Cheng et al 197 employed a water-induced phase separation approach to fabricate an MXene/AgNW/PU composite foam with a low density of 0.15 g cm −3 . 1D AgNWs and 2D MXene synergistically built a 3D framework as a conductive network, exhibiting high EMI shielding ability (50 dB).…”

“…[32] Since then, researchers have used the same method to etch other monatomic transition metal carbides such as Ti 2 AlC, Ta 4 AlC 3 , Nb 2 AlC with HF as etching solvent. MXene has been deemed as a promising candidate in various areas such as gas separation, [33][34][35] electromagnetic shielding, [36][37][38] catalysis, [39,40] and water purification [41,42] because of its excellent electrical conductivity, surface hydrophilicity, rich surface functional groups, good modification capacity, and so on. [43][44][45][46][47] Meanwhile, the application of MXene in the domains of corrosion protection has also been probed.…”

Incorporating MXene nanomaterials in coating is an effective strategy to fabricate anticorrosive coatings with superior corrosion resistance, depending on its characteristic structure and nature. However, it may accelerate the corrosion rate of metal once forming galvanic corrosion by direct contact with the substrate due to its high conductivity and hydrophilicity. Herein, 1H,1H,2H,2H‐perfluorodecyltrichlorosilane (PFDTS) is used to functionalize Ti3C2Tx nanosheets to obtain superhydrophobic Ti3C2Tx hybrids, which greatly enhances the hydrophobicity of Ti3C2Tx nanosheets. Then, a new strategy is designed to construct superhydrophobic Ti3C2Tx/epoxy/cerium conversion (STECC) composite coating with sandwich‐like structure, which consists of bottom cerium conversion coating, intermediate epoxy coating, and top superhydrophobic Ti3C2Tx coating layer. The underlying cerium conversion layer and intermediate epoxy coating acted as the protective coating not only improve the corrosion protection ability of substrate but also isolate the top superhydrophobic Ti3C2Tx layer from direct contact with the substrate, which can eliminate direct contact between MXene and Mg alloy to further restrain the corrosion–promotion effect of Ti3C2Tx. The STECC with unique structure exhibits excellent water repellency, robust mechanical and chemical stability. Electrochemical experimental results demonstrate that the modified MXene nanosheets can remarkably improve the corrosion protection performance of STECC composite coating, and the impedance modulus of STECC coating reaches the value of approximately 7.49 × 106 Ω cm2 and increases four orders of magnitude compared with the Mg substrate. The composite coating studied here may offer valuable insights and inspiration toward developing MXene‐based coating for high‐performance anticorrosion.

“…Polymer sponges are a kind of continuous natural three-dimensional (3D) soft templates, which can effectively form continuous filler interconnected networks through simple dipping or coating [ 7 – 9 ]. Long-range continuous electrical [ 10 – 12 ] and thermal network [ 13 – 15 ] is an essential structural feature for the formation of multifunctional polymer composites with high performance. The 3D soft templates represented by polyurethane (PU) sponge [ 11 , 16 – 19 ], melamine foam [ 10 , 20 – 22 ], and polyimide foam [ 23 , 24 ], combined with functional fillers, can easily obtain the continuous interconnected structure.…”

The multi-functionalization of polymer composites refers to the ability to connect multiple properties through simple structural design and simultaneously achieve multi-performance optimization. The large-scale design and mass production to realize the reasonable structure design of multifunctional polymer composites are urgently remaining challenges. Herein, the multifunctional MXene/graphene/polymer composites with three-dimensional thermally and electrically conductive network structures are fabricated via the utilization of the microstructure of the soft template, and a facile dispersion dip-coating approach. As a result, the polymer composites have a multi-performance improvement. At the MXene and graphene content of 18.7 wt%, the superior through-plane thermal conductivity of polymer composite is 2.44 W m−1 K−1, which is 1118% higher than that of the polymer matrix. The electromagnetic interference (EMI) shielding effectiveness of the sample reaches 43.3 dB in the range of X-band. And the mechanical property of the sample has advanced 4 times compared with the polymer matrix. The excellent EMI shielding and thermal management performance, along with the effortless and easy-to-scalable producing techniques, imply promising perspectives of the polymer composites in the next-generation smart electronic devices.
