“…As generally known, most traditional EMI shielding materials are metal-based, apparently restricting their application in flexible devices. , Therefore, a novel material with superior EMI shielding effectiveness (SE) has aroused extensive attention. Carbon nanomaterials and nanocomposites, such as carbon nanotubes (CNTs), graphene oxide (GO), and reduced graphene oxide (rGO), have been developed in recent years for EMI shielding. − Qin and Brosseau offer a perspective on the experimental efforts toward the development of microwave absorbers composed of carbonaceous inclusions in a polymer matrix.

MXene aerogels with a porous microstructure are a promising electromagnetic interference (EMI) shielding material due to its low density and excellent electrical conductivity, which has attracted widespread attention. Compared with traditional EMI shielding materials that rely on reflection as the primary mechanism, MXene aerogels with absorption as the dominant mechanism have greater potential for development as a novel EMI shielding material because of its ability to reduce environmental contamination from reflected electromagnetic (EM) waves from materials. In this study, a novel Ti3C2T x MXene/PEDOT:PSS hybrid aerogel was presented by freeze-drying and thermal annealing using few-layered Ti3C2T x MXene and the conductive polymer poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS). PEDOT:PSS not only improved the gelling ability of Ti3C2T x but also successfully established a conductive bridge between MXene nanosheets. The experimental results demonstrated that the hybrid aerogel exhibited an obvious porous microstructure, which was beneficial for the multiple scattering of EM waves within the materials. The EMI shielding effectiveness and specific shielding effectiveness reached up to 59 dB and 10,841 dB·cm2·g–1, respectively, while the SE R /SE T ratio value was only 0.05, indicating superior wave absorption performance. Furthermore, the good impedance matching, due to the electrical conductance loss and polarization loss effect of the composites, plays a critical role in their excellent wave absorption and EMI shielding performance. Therefore, this work provides a practical approach for designing and fabricating lightweight absorption-dominated EMI shielding materials.

The study proposes a novel way of amalgamating three different materials to develop an effective electromagnetic interference (EMI) shielding material by completely utilizing the distinct properties of each one. First and foremost, binary composites have been prepared by combining with various weight of silver (1, 2, and 3 g) and constant weight percentages of glass fiber. The synthesis of the glass fiber‐silver‐PANI ternary composite is then brought about by PANI particles precisely encased on the surface of the glass fiber‐silver binary composite. The intertwining of a thin PANI coating on the binary composite is done successfully via simple in‐situ polymerization of aniline using lime juice as the dopant. The structural properties have been studied with XRD and FT‐IR. The SEM analysis reveals the effectual distribution of PANI on binary composite. The thermal stability of the composites has been studied using TG analysis. Most importantly, the glass fiber‐silver‐PANI ternary composite shows significantly high EMI shielding effectiveness up to 41 dB in the x‐band region.
