The development of lightweight and integration for electronics requires flexible films with high thermal conductivity and electromagnetic interference (EMI) shielding to overcome heat accumulation and electromagnetic radiation pollution. Herein, the hierarchical design and assembly strategy was adopted to fabricate hierarchically multifunctional polyimide composite films, with graphene oxide/expanded graphite (GO/EG) as the top thermally conductive and EMI shielding layer, Fe3O4/polyimide (Fe3O4/PI) as the middle EMI shielding enhancement layer and electrospun PI fibers as the substrate layer for mechanical improvement. PI composite films with 61.0 wt% of GO/EG and 23.8 wt% of Fe3O4/PI exhibits high in-plane thermal conductivity coefficient (95.40 W (m K)−1), excellent EMI shielding effectiveness (34.0 dB), good tensile strength (93.6 MPa) and fast electric-heating response (5 s). The test in the central processing unit verifies PI composite films present broad application prospects in electronics fields.

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.

“…In this regard, it is required to incorporate conductive and magnetic fillers into polymer matrix, imparting both electrical and magnetic dipoles: the two key parameters in the design of materials with greater EMI shielding effectiveness. [ 8 ] Among various available conductive fillers, carbon‐based materials, including carbon black (CB), [ 9 ] carbon fiber, [ 10,11 ] reduced graphene oxide (rGO) [ 12 ] , and carbon nanotube (CNT), [ 13,14 ] are one of the top candidates that could potentially improve the required properties. Particularly, multiwall carbon nanotubes (MWCNTs) have been widely employed to fabricate EMI shielding polymer composites due to their large aspect ratio, high electrical conductivity, remarkable mechanical properties, and relative low cost.…”

Electromagnetic interference (EMI) shielding rubber nanocomposites were fabricated via a simple rubber roll milling technique based on the filler distribution behavior in the immiscible natural rubber (NR) and acrylonitrile-butadiene (NBR) (50/50) blends with varying amounts of multiwall carbon nanotubes and Fe 3 O 4 nanoparticles. All nanocomposites showed a co-continuous phase structure, while the distribution behavior of filler was diverse correlated with the filler content and type. The mechanical properties, electrical conductivity, and EMI shielding effectiveness (SE) of rubber composites were characterized. The maximum EMI SE of 29.4 dB at 12.4 GHz was achieved in the rubber composites loaded with 15 phr MWCNTs and 15 phr Fe 3 O 4 nanoparticles. The EMI shielding mechanisms of such materials were also discussed. The observation in this work provided a possible idea to the industrial manufacture electromagnetic interference shielding rubber nanocomposites, and contributed to expanding its application fields with higher mechanical property requirements and flexibility.
