“…Moreover, the miniaturization and integration of electronic circuits and components put forward the request of flexible portable microwave absorption electronic devices [5,6]. Two-dimension (2D) materials, such as reduced graphene oxide (RGO) [7][8][9][10], MoS 2 [11][12][13][14][15], and new member Mxene [16][17][18][19], are usually applied as microwave absorber owing to their high specific surface area and abundant functional groups as well as defects, which will enhance the propagation paths of incident electromagnetic wave (EMW) inside absorbers by scattering effect and increase the loss through polarization relaxation loss. As one of the 2D material, MoS 2 has adjustable electrical property and can change between insulators and semiconductor metals.…”

Phase engineering is an important strategy to modulate the electronic structure of molybdenum disulfide (MoS2). MoS2-based composites are usually used for the electromagnetic wave (EMW) absorber, but the effect of different phases on the EMW absorbing performance, such as 1T and 2H phase, is still not studied. In this work, micro-1T/2H MoS2 is achieved via a facile one-step hydrothermal route, in which the 1T phase is induced by the intercalation of guest molecules and ions. The EMW absorption mechanism of single MoS2 is revealed by presenting a comparative study between 1T/2H MoS2 and 2H MoS2. As a result, 1T/2H MoS2 with the matrix loading of 15% exhibits excellent microwave absorption property than 2H MoS2. Furthermore, taking the advantage of 1T/2H MoS2, a flexible EMW absorbers that ultrathin 1T/2H MoS2 grown on the carbon fiber also performs outstanding performance only with the matrix loading of 5%. This work offers necessary reference to improve microwave absorption performance by phase engineering and design a new type of flexible electromagnetic wave absorption material to apply for the portable microwave absorption electronic devices.

“…Examples include magnetically filled or coated carbon nanotubes [64][65][66][67][68], ferrite-carbon [69][70][71][72] and ferrite-graphene [73][74][75][76] composites. To further upgrade the attenuation, there have recently been significant efforts in constructing hybrid hierarchical composite nanostructures with complicated geometrical morphologies [77][78][79][80][81][82][83][84][85][86]. This includes graphene oxide/nickel nanofibers with hierarchical core/shell structure and vertically aligned graphene edge planes [78] or ZnFe 2 O 4 particles synthesised inside porous hollow carbon microspheres [77], where the multiple interfaces in the structure improved interfacial polarisation and thus the overall absorbing capabilities.…”

Using carbon-fibre-reinforced polymer (CFRP) composites for electromagnetic interference (EMI) shielding has become a rapidly emerging field. This state-of-the-art review summarises all the recent research advancements in the field of electromagnetic shielding properties of CFRP composites, with exclusive attention paid to experimental work. It focuses on (1) important mechanisms and physical phenomena in the shielding process for anisotropic carbon-fibre composites and (2) shielding performance of CFRP materials as reported in the literature, with important performance-affecting parameters. The key properties which directly influence the shielding performance are identified, the most critical being the carbon-fibre concentration along with length for discontinuous carbon-fibre-filled polymers and the lay-up for continuous carbon-fibre-reinforced composites. The effect of adding conductive inclusions such as metal or carbon nanotubes is also reviewed. It is emphasised that processing conditions are strongly linked with the shielding properties of a composite. This is a first review, which covers all the recent advancements in the field of shielding properties of carbon-fibre-reinforced composites, with detailed analysis of factors influencing these properties and clear distinction between continuous and discontinuous reinforcement. It is shown that CFRP composites make a good candidate as an EMI shielding enclosure material.

Core–shell nanoparticles are a unique class of nanostructured materials, which received significant attention in the last two decades owing to their exciting properties and a wide variety of applications. By judiciously tuning the “core” as well as the “shell”, an assortment of “core–shell” nanostructures can be obtained with tailorable properties which can play pivotal roles in designing materials for electromagnetic interference (EMI) shielding and microwave absorption. In recent times when the use of high-end electronics has been on the rise, electromagnetic pollution is inevitable and it affects every walk of life. Among numerous e-pollutions, a recently highlighted domain that has far-reaching consequences is electromagnetic interference. EMI is the disturbance created during an electronic device’s operation when it is in the vicinity of an electromagnetic field caused by another electronic or electric device. Since EMI decreases the lifetime and degrades the performance of the electronic instruments and even affects human health, it is crucial to protect sophisticated instruments and components from EM interference. High-performance EMI shields capable of attenuating microwave propagation efficiently have been developed in the past decade. Herein, in this review, we attempted to provide a logical guide to various “core–shell” nanostructures (≤500 nm) that have been synthesized in the past decade for the application in microwave absorption and EMI shielding. The prime focus of this review article is to highlight the fundamental concept of EMI shielding and microwave absorption that have been reported for various systems in the literature along with various synthetic and fabrication strategies in designing suitable broadband EM absorbers/screeners. Finally, we also made an effort to provide a holistic outlook and perspective in which upcoming research will continue to flourish.
