Summary: NiCo layered double hydroxide (LDH) nanowire arrays were grown on carbon fabric via hydro-thermal processes, then annealed into NiCo2O4 nanowire arrays at 350 degrees C, and finally melted into NiCo2 particles at 800 degrees C. The influence of these NiCo compounds on the electromagnetic interference (EMI) shielding performance of carbon fabric was investigated. The results showed that LDH nanowire arrays enhanced the microwave attenuation of carbon fabric, while NiCo2O4 nanowire arrays improved the shielding effectiveness of carbon fabric mainly through multiple reflections. Only NiCo2 particles could improve the surface reflection and enhance internal absorption simultaneously, leading to a composite with better EMI shielding performance.

Summary: This study proposes a broadband metastructure absorber by manipulating the complex permittivity and complex permeability of vapor-grown carbon fiber (VGCF) and flaky carbonyl iron particles (CIP).

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
