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: A solvent-free GO@Fe3O4 nanofluid hybrid water-based sizing agent was prepared and applied to improve the interface properties and thermal conductivity of carbon fiber reinforced polymers. The GFNF CF/EP composites showed significantly enhanced performance compared to commercial CF/EP composites, with improvements in interfacial properties and thermal conductivity. The enhanced properties were attributed to the uniform adhesion of GFNF to the CF surface, promoting physical-chemical interaction, stress dispersion, and prevention of cracking, as well as the formation of continuous thermal conduction pathways at the interface.

Summary: In this study, La1-xSrxMnO3 (LSMO) ceramic was successfully fabricated and both Lorentz-like and Drude-like negative permittivity were observed by adjusting the content of Sr2+. With the increase of Sr2+ content, the amplitude of dielectric resonance decreased and the resonance frequency shifted to a lower frequency region. When the Sr2+ content reached 0.7, the Drude-like negative permittivity dominated. The low tand value of LSMO was also observed. The generation and regulation mechanism of negative permittivity were clarified.

Summary: The recent advancement of metacomposites with negative permittivity provides a new research approach for the design and construction of electromagnetic shielding materials. In this study, Ni/YIG metacomposites were fabricated using a liquid impregnation approach and their electromagnetic properties were explored at MHz and Ku bands. With an increase in Ni content, isolated Ni particles formed interconnected networks in the composites, resulting in changes in conducting mechanism and reactance characteristic. The composites with high Ni contents exhibited a negative permittivity behavior, attributed to low-frequency plasma state of free electrons in the completed Ni networks. The dispersion of negative permittivity at frequencies below 10 MHz was influenced by isolated metal particles and could be well described by the Drude-Lorentz model. A notable shielding effectiveness of 33.1 dB was achieved at Ku band, primarily due to the impedance mismatch caused by the negative permittivity. The inductive conducting networks were crucial building blocks for achieving negative permittivity and improving electromagnetic shielding performance. This work provides guidance for designing electromagnetic shielding metacomposites and promotes further development in this field.
