Due to the advancements in the electronics industry, the demand for new electromagnetic interference (EMI) shielding and microwave absorption (MA) materials has increased significantly in recent decades. Researchers are investigating a variety of new materials to replace conventional metal sheets in response to these growing demands. Consequently, there is a growing interest in lightweight EMI shielding materials that can meet the demand for lightweight and highly integrated electronic equipment. 2D structural transition metal dichalcogenides (TMDCs) are good candidates for EMI shielding and MA due to their unique properties. This article examines the latest developments in TMDCs and their composite nanomaterials, focusing on their EMI shielding effectiveness and MA performance. The investigation includes a thorough examination of these materials’ shielding effectiveness, maximum reflection loss value, and effective absorption bandwidth. Moreover, this review analyzes the challenges and opportunities that arise in the development of TMDCs.

With the development of modern society and technology, increased levels of electromagnetic pollution have created a greater demand for advanced electromagnetic wave absorption materials for use in both civilian and military applications. Three-dimensional graphene (3DG) has excellent potential for use in the field of microwave absorption (MA) due to its unique porous network structure, low density, and large specific surface area. However, the dielectric loss performance will lead to poor impedance matching performance, making it unsuitable for use as a single absorber. To overcome this shortcoming, 3DG-based composites have been developed by combining 3DG with other absorbing materials to create structures with improved impedance matching performance and absorption efficiency. Compared to other review articles, this Review comprehensively summarizes the preparation methods of 3DG and discusses the advantages and disadvantages of various methods. Subsequently, based on the types of composite materials, the research progress of 3DG-based composite absorptive materials is discussed. Finally, the obstacles to the widespread application of composite absorptive materials based on 3DG are summarized along with future research directions. Finally, the barriers to the widespread use of 3DG-based composite absorbing materials and future research directions are summarized.

Herein, multiwalled carbon nanotube (MWCNT)/silicon nitride (Si3N4)/polyaniline (PANI) ternary composites are prepared. The preparation method involves attaching carboxyl groups to acid‐modified MWCNT surfaces and amino groups to Si3N4 surfaces modified using a silane‐coupling agent. Then they are combined to binary composites using the solvent‐thermal method. Finally, the ternary composites are prepared by coating PANI on the surface of MWCNT/Si3N4 composites in situ polymerization. The morphology and structure of these composites are characterized through X‐ray diffraction, Fourier‐transform infrared spectroscopy, scanning electron microscopy, transmission electron microscopy, and X‐ray photoelectron spectroscopy. Results show that the reflection loss at 8.8 GHz reaches −42.57 dB when the feeding ratio of MWCNT:Si3N4:PANI is 3:20:40 and the corresponding effective absorption bandwidth reaches 4.06 GHz when the thickness is 3.5 mm. A conductive network with effective electron leaps is formed among MWCNT, Si3N4, and PANI, which increases the conductive loss of the composites. An abundant number of interfaces have formed in the composite materials and promoted dielectric loss. Multiple loss mechanisms and good impedance matching performance endow MWCNT/Si3N4/PANI with excellent microwave absorption performance, and the incorporation of Si3N4 enables the composites to exhibit satisfactory high‐temperature resistance. Thus, these performances render the composites promising materials to address increasing electromagnetic pollution, particularly at high temperatures.
