“…Moreover, when the applied voltage increased in gradient, the Joule heating temperature of the rGO/AgNWs paper responded quickly without significant hysteresis, which suggested that the rGO/AgNWs paper had great application potential in the field of intelligent temperature control (Nan et al, 2020). To the best of our knowledge, the rGO/AgNWs paper presented a higher Joule heating temperature at low applied voltage than most other thermal conductors (Chung et al, 2018;Bharat et al, 2019;Dai et al, 2019;Kim et al, 2020;Nan et al, 2020;Yang et al, 2020;Yang et al, 2020;Liu et al, 2022). In order to evaluate the long-term stability and reliability of the rGO/ AgNWs paper, the temperature variations versus time at a constant applied of 3 V were characterized, as shown in Figure 7D.…”

Silver nanowire (AgNW) has excellent thermal conductivity, which is an ideal material for fabricating flexible electrical heating materials. However, the poor stability of AgNWs is far from meeting the requirements for the practical application of electrical heating materials. Herein, by imitating the layered structure of nacre, the reduced graphene oxide (rGO)/AgNWs paper with a nacre-like structure was successfully prepared using a simple gravity-induced deposition approach. The obtained rGO/AgNWs paper showed excellent electrical conductivity (19.61 Ω/sq) and good pattern adjustability at the rGO to AgNWs ratio of 1:1. More importantly, the rGO/AgNWs paper exhibited high resistance to oxygen and water vapor, thus realizing long-term stability and reliability. Moreover, the design of a nacre-like structure could improve the thermal management performances of rGO/AgNWs paper, making it achieve a high Joule heating temperature (∼215.83°C) at low supplied voltages (3 V), the rapid response time (∼12 s) and long-term heating stability. These results indicate that the prepared rGO/AgNWs paper promises to be an electrical heating component with high chemical stability for thermal management electric materials.

“…The MXene/Ag skeleton promoted the formation of heat-conduction paths in the matrix. Therefore, the combined use of MXene and Ag significantly improved the thermo-conducting properties of epoxy matrices and has been exploited in recent works with Ag nanoparticles [ 55 ] and using Ag nanowires (AgNW) [ 56 ]. Compared with pure epoxy, the 3D-oriented interconnection significantly improved the TC to 1.17 W/m⋅K in the MXene/AgNW/ER composites.…”

“…Moreover, networks can decrease the percolation threshold of conductive fillers. In the following works, 3D hybrid porous structures were fabricated from Ti 3 C 2 T x MXene with reduced graphene oxide [ 73 ], carbon foams [ 74 ], natural nanofibers [ 75 ], and silver nanowires [ 56 ] by directional-freezing and freeze-drying methods. Then, fillers were embedded in an epoxy matrix, providing the necessary strength and stabilization of the preformed aerogels, using a vacuum-assisted impregnation technique.…”

“…On the other hand, 1D AgNWs are considered promising filler candidates for fabricating electromagnetic-interference-shielding materials due to their outstanding conductivity. Three-dimensional aerogels of MXene/silver nanowires (AgNWs) used to reinforce epoxy resin nanocomposites have just been reported [ 56 ]. In this publication, hybrid aerogels of MXene/AgNWs enhanced the EMI-shielding performance and remedied the typical weak adhesion between the cylindrical structure of AgNW and a substrate through hydrogen bond interactions with MXenes.…”

Epoxy resins are thermosets with interesting physicochemical properties for numerous engineering applications, and considerable efforts have been made to improve their performance by adding nanofillers to their formulations. MXenes are one of the most promising functional materials to use as nanofillers. They have attracted great interest due to their high electrical and thermal conductivity, hydrophilicity, high specific surface area and aspect ratio, and chemically active surface, compatible with a wide range of polymers. The use of MXenes as nanofillers in epoxy resins is incipient; nevertheless, the literature indicates a growing interest due to their good chemical compatibility and outstanding properties as composites, which widen the potential applications of epoxy resins. In this review, we report an overview of the recent progress in the development of MXene/epoxy nanocomposites and the contribution of nanofillers to the enhancement of properties. Particularly, their application for protective coatings (i.e., anticorrosive and friction and wear), electromagnetic-interference shielding, and composites is discussed. Finally, a discussion of the challenges in this topic is presented.

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.
