Summary: Epoxy polymers were modified with a hybrid nanofiller containing graphene nanoplatelets (GNPs) and carbon nanotubes (CNTs) at a mass ratio of 9:1, resulting in a significant increase in electrical conductivity and fracture energy. The reduced percolation threshold was attributed to CNTs, while the increased toughness was mainly due to GNPs through crack deflection. The toughening contribution of the hybrid nanofiller was accurately predicted using analytical modeling.

Summary: Novel carbon nanostructures, carbon nanobuds and nanoballs, have been successfully synthesized on the surface of graphene using the electrochemical method. Under a certain potential, carbon nanobuds are grown in situ on the surface of graphene, and with the increase of potential, these nanobuds grow into nanoballs and exfoliate from the graphene surface. Graphene undergoes oxidation at higher potentials, resulting in the formation of graphene oxide fragments.

Summary: This study fabricated PMMA/GNPs conductive composite films with different morphologies using four fabrication techniques and systematically investigated the morphologies of dispersed GNPs and their electrical properties in both in-plane and perpendicular direction. The percolation thresholds and conductivities of the composites varied significantly with different fabrication techniques, and the differences were explained in terms of GNPs size, orientation, distribution, and dispersion state.

Summary: Both graphene and carbon nanotubes can improve the crosslinking density, reduce rolling resistance, and wet-skid resistance of NR composites. Compared to CNTs, graphene degrades manufacturing safety and cure rate, but exhibits a higher reinforcing effect in terms of tensile strength, modulus, and hardness. Additionally, graphene/NR composites show better aging resistance than CNTs/NR. On the other hand, CNTs can improve manufacturing safety and cure rate, maintain higher tear strength, and provide better tensile fatigue and wear resistance, as well as lowering rolling resistance while maintaining higher wet-skid resistance in comparison to graphene.

Summary: In this study, an ultralight magnetic composite foam with hierarchical impedance structure was developed by electrostatic self-assembly of MXene on graphene skeletons and subsequent hydrothermal anchoring of FeS clusters. The composite foam exhibited high microwave absorption performance, with a minimum reflection loss of -47.17 dB and an effective absorption bandwidth of 6.15 GHz at a thickness of 4.78 mm. The microwave absorption performance of the foam could be further optimized by controlling the loading of MXene and applying low-temperature thermal treatment.
