“…The poly (vinyl alcohol)/MXene (PVA/MXene) multilayered composite reported by Jin et al exhibits 44.4 dB (wt.%-19.5%) of EMI SE (SE R -8.3 dB) with 0.027 mm of thickness and decrease with decreasing MXene loading in the PVA matrix. MXene in a PVA matrix has a similar EC trend and diminishes with less loading of MXene filler (Table 3) [51][52][53]. Further, the Xu et al study shows that the PVA/MXene foam considerably minimized the EMI SE and exhibits 28 dB of EMI SE with a lower SE R (2 dB), which is due to the differences in EC and its porous nature.…”

The two Dimensional (2D) materials such as MXene and graphene, are most promising materials, as they have attractive properties and attract numerous application areas like sensors, supper capacitors, displays, wearable devices, batteries, and Electromagnetic Interference (EMI) shielding. The proliferation of wireless communication and smart electronic systems urge the world to develop light weight, flexible, cost effective EMI shielding materials. The MXene and graphene mixed with polymers, nanoparticles, carbon nanomaterial, nanowires, and ions are used to create materials with different structural features under different fabrication techniques. The aerogel based hybrid composites of MXene and graphene are critically reviewed and correlate with structure, role of size, thickness, effect of processing technique, and interfacial interaction in shielding efficiency. Further, freeze drying, pyrolysis and hydrothermal treatment is a powerful tool to create excellent EMI shielding aerogels. We present here a review of MXene and graphene with various polymers and nanomaterials and their EMI shielding performances. This will help to develop a more suitable composite for modern electronic systems.

“…Ti 3 C 2 T x MXene/graphene hybrid foams have been designed for EMI shielding applications. [71] Hybrid foams with varying MXene to GO ratio were produced using simple vacuum drying of frozen solutions at −65 °C followed by thermal reduction at 300 °C for 1 h. The density of a pure rGO foam was 3.1 mg cm −3 , while the hybrid foam with a MXene to graphene ratio of 1:1 was 7.2 mg cm −3 . Ti 3 C 2 T x MXene has a higher density than graphene, and thus the addition thereof increased the density of the hybrid foam.…”

Since the first report on electromagnetic interference (EMI) shielding of 2D Ti 3 C 2 T x in 2016, MXenes have captured the leadership position among lightweight shielding materials due to many advantages, including their excellent shielding performance, outstanding metallic conductivity, low density, large specific surface area, tunable surface chemistry, and solution processability. MXenes triggered a huge interest in the materials research community, leading to over 100 reported publications on MXenes' EMI shielding within 3 years. Many MXenes composites and hybrids in different structural forms, such as compact and laminate structures, layer-by-layer assemblies, porous foams and aerogels, and segregated structures, have been explored to further improve the intrinsic EMI shielding properties of MXenes. This article comprehensively reviews the recent advancements in MXene-based EMI shielding materials with different structural morphologies and provides an insight into future challenges and guidelines for finding material solutions for the nextgeneration shielding applications.

“…Such overwhelming merits make them promising candidates for microwave absorption, electromagnetic interference shielding, flexible electronics, and solar energy conversion. Thus far, there are several methods for preparing MXene aerogels including (1) direct freeze-drying of MXene NC dispersions, 16,25,35,36 (2) calcination after freeze-drying of MXene NC dispersions, [37][38][39][40][41] and (3) freeze-drying of MXene hydrogels. 5,6,12,28,[42][43][44][45][46][47] In all these methods, the sublimation of ice crystals from frozen dispersions or hydrogels was necessary for obtaining MXene aerogels.…”
