Summary: A strategy of constructing three-dimensional network structures of graphene/CNT/polypyrrole by electrochemical deposition is proposed to improve the EMI shielding effectiveness of polypyrrole composite films. The graphene/CNT/polypyrrole films consist of graphene/CNT substrates as skeletons and polypyrrole as bridges to form percolation networks in the multiphase and multihierarchical nanocomposites. With a deposition time of 80 min, the polypyrrole content increases to 30 wt%, the conductivity improves by 27.7%, and the EMI shielding effectiveness improves by 11.4% at X-band. The final film thickness is 249 μm, the conductivity is 3.06 S/mm, and the average EMI shielding effectiveness is 59.6 dB.

Summary: Carbon nanotube/polylactic acid (CNT/PLA) materials with different CNT contents were fabricated using 3D printing technology. These materials demonstrated light weight, environmental protection, and good chemical stability. 3D-printed CNT/PLA composites showed improved mechanical properties, conductive behaviors, and electromagnetic interference (EMI) shielding compared to pure 3D-printed PLA composites. The EMI shielding effectiveness (SE) of the composites increased with higher CNT content, reaching up to 47.1 dB (shielding 99.998% of electromagnetic energy) at 15 wt% CNT. The EMI shielding mechanism of the composites was mainly absorption loss, accounting for over 80% of the total shielding loss. These excellent properties make 3D-printed CNT/PLA composites highly promising for industrial and aerospace applications.

Summary: Lightweight, flexible, and water-repellent shielding materials are crucial in managing radiation pollution for modern electronic devices. In this study, carbon nanotube-fastened graphene composite film was demonstrated to have high EMI shield performance due to the interconnected bubbles formed by the curved and fastened morphology of reduced graphene. Additionally, the thin hydrophobic SiO2 coating on the film's surface provided stable water repellence even in severe conditions.

Summary: The adoption of metal-organic frameworks (MOFs) has significantly enhanced the electromagnetic interference (EMI) shielding performance, which has gained attention due to the widespread use of electronics and wireless communication. The tunable molecular scaffold architecture of MOFs allows for customizable magnetic and electrical properties, making them ideal for shielding EM waves at multiple scales. This review highlights the importance of molecular-, nano-, micro-, and macro-scale structural design in MOF-based EMI shields, outlines current design strategies, and examines the factors hindering their widespread utilization. Future research directions for the rational design of next-generation MOF-based EMI shields are also proposed to address the concerns regarding EM radiation.

Summary: High-performance epoxy resin (EP) composites with excellent thermal conductivity and electromagnetic shielding properties are fabricated by using 1D carbon nanotubes and 2D silver-modified boron nitride nanoplates (CNT/AgBNs) to construct microscopic 3D networks on long-range carbon fiber (CF) felt skeletons. The combination of CNT/AgBNs improves the interfacial bonding and phonon scattering at the interface, leading to enhanced thermal conductivity of the EP composites. The unique structure of CF felt and insulating BNs protect the through-plane insulating properties, while the multiple interfaces of stacked AgBNs and heterointerface promote the electromagnetic shielding properties.

Summary: Porous composites with a regulated inter-connected hole structure and controllable porosity were successfully prepared via a facile freeze-drying method using cotton cellulose nanofiber (CCNF) as the main framework and aramid nanofiber (ANF) as a reinforcer. The introduction of a small amount of ANF improved the thermal collapse resistance of the porous materials. The porous composites exhibited decreased porosity and increased pressure drop performance with increased addition of CCNF and ANF. The as-prepared porous composite could be a promising candidate in the tobacco field.
