Abstract

Abstract: The roll-out of 5 G communication has intensified electromagnetic (EM) pollution that not only disturbs electronic devices but also raises health concerns. Here, we report a hierarchical “face-to-point” architecture in which 2D MoS₂ nanosheets are vertically grown on carbon fibers (CFs) and 0D Ag nanoparticles (AgNPs) are selectively anchored in the inter-sheet gaps. The resulting heterodimensional co-decoration acts as a 2D-0D synergistic “nano-nail” that simultaneously reinforces the interface and provides broadband EM attenuation. Hot pressed CF reinforced polyether ether ketone (CF/PEEK) composites exhibit a 66.21 % increase in interlaminar shear strength (ILSS, 95.44 MPa) and a 58.21 % boost in electromagnetic interference shielding effectiveness (EMI SE_T, 32.29 dB). Additionally, the UCF-M14@AgNPs demonstrated outstanding performance in electromagnetic wave (EMW) absorption, with a minimum reflection loss (RL_min) reaching -67.11 dB and an effective absorption bandwidth (EAB) extending up to 4.00 GHz. This dual-scale interfacial engineering strategy delivers structural composites that merge superior mechanical integrity with lightweight EM protection capability, offering immediate potential for aerospace and next-generation electronics.
