Previous research predominantly emphasized the incorporation of magnetic fillers, often neglecting their synergistic integration with spatial architecture, thereby constraining the multifunctionality of EMI shielding systems. In contrast, layer-by-layer (LBL) fabrication technology offered precise control over microstructures and enabled multifunctional integration, which had been effectively applied in areas such as supercapacitors, controlled drug release, nanofiltration membranes and EMI shielding. By constructing tailored layered configurations, this approach facilitated tunable attenuation of electromagnetic waves. Herein, aramid nanofibers (ANF), carbon nanotubes (CNT), MXene and cobalt ferrite (CoFe₂O₄) were employed to fabricate a multilayer film featuring a magnetic-electric bi-continuous gradient structure via LBL assembly. Owing to its hierarchical architecture, the (Z₁-Z₂-Z₃)CoFe₂O₄@CNT/ANF-PMXene-CNT/ANF ((Z₁-Z₂-Z₃)CoC/A-PM-C/A) films demonstrated exceptional EMI shielding performance. Particularly, the (80-40-10)CoC/A-PM-C/A composite film achieved a high EMI shielding effectiveness (EMI SE) of 63.6 dB and exhibited a low reflection coefficient (R) of 0.613, while maintaining favorable mechanical properties, including a tensile strength of 51.2 MPa and toughness of 5.67 MJ m⁻³. Simultaneously, the films exhibited superior thermal camouflage capability with a mid-infrared (IR) emissivity as low as 2.61% in the 7∼17 μm range, and displayed effective Joule-heating characteristics.

Although GO is a flexible resistive-switching medium, the majority of memristors still primarily function in binary, filamentary modes after embedding GO in polymer matrices. In this study, we present a polymer-free, drop-cast GO device that isolates intrinsic metal/GO interfacial effects, allowing for low-current, forming-free analog switching with robust synaptic functions and state-dependent capacitance. The response can be adjusted from filamentary digital switching to self-rectifying analog behavior by modifying the top electrode (Cr, Al, Ag). Notably, all devices operate at low current without requiring a forming step, a key advance for enhancing endurance and scalability. Micro-Raman analysis further reveals thermal-driven reduction of GO under prolonged cycling, directly linking material changes to device degradation. Most strikingly, the Cr/GO/Al system exhibits rich neuromorphic dynamics, including short-term memory, long-term potentiation/depression, and pulse-width-dependent learning with non-monotonic relaxation, as well as precise multi-bit weight updates with a resolution of up to 9 bits.

Through the condensation reaction between its aldehyde groups and active sites in pitch (phenolic hydroxyl groups, aromatic ring side chains), multiple small-molecular-weight aromatic hydrocarbons in pitch were connected via C–O, C–C, or C(O)–O bonds. This design constructed a three-dimensional network structure of modified pitch, enabling more efficient and thorough oxidative cross-linking.
