Summary: Nanocomposites consisting of CuxCo1-xFe2O4-rGO-TPU exhibit highly efficient electromagnetic interference shielding, with maximum shielding effectiveness values of 42.9 dB, 46.2 dB, and 58.8 dB. This performance is attributed to good impedance matching, conductivity, dielectric properties, and magnetic loss. These materials are promising candidates for lightweight, flexible, and highly efficient EMI shielding.

Summary: In this work, Fe3O4@anisotropic reduced graphene oxide aerogel/epoxy (Fe3O4@AGA/EP) nanocomposites were successfully fabricated, showing outstanding electromagnetic interference (EMI) shielding performance and mechanical properties. The Fe3O4@AGA/EP nanocomposites were obtained by one-step hydrothermal reduction method and unidirectional freezing approach to prevent the agglomeration of Fe3O4 and graphene oxide (GO). The research provides a potential solution for the development of EP-based composites with high EMI shielding performance and mechanical properties.

Summary: Nickel nanoparticle-decorated reduced graphene oxide nanocomposites (NiG) were prepared using a one-step microwave-assisted solvothermal method. NiG nanocomposites were further heated up to 800°C under an inert atmosphere to modify their structural and electromagnetic properties. These NiG nanocomposites were then used as nanofillers in a SEBS polymer matrix to create NiG-800(50)-SEBS and NiG-800(70)-SEBS nanocomposites. The addition of NiG-800 to SEBS resulted in an increase in Young's modulus and high-performance electromagnetic wave absorption.

Summary: Sonochemically synthesized superparamagnetic ZnFe2O4 nanoparticles with controlled structural properties show superparamagnetic behavior. Embedding the prepared nanoparticles and reduced graphene oxide in a polyurethane resin matrix provides shielding against electromagnetic pollution, with high absorption of electromagnetic waves and effective impedance matching. The synergistic effect of ZnFe2O4 and RGO in the PUR matrix leads to significant absorption of electromagnetic waves, offering an innovative approach for lightweight nanocomposites.

Summary: A composite material of reduced graphene oxide (rGO) coated with metal-organic framework (MOF) HKUST-1 was synthesized using a simple hydrothermal method, showing excellent electromagnetic shielding effectiveness attributed mainly to dielectric loss and synergic effects between rGO and HKUST-1. The introduction of HKUST-1 prevented sheet layers from aggregating and decreased impedance mismatching by limiting reflection, leading to enhanced shielding properties over a wide frequency range.
