Aramid Nanofibers/Inorganic Nanocomposite Materials: Design Strategies, Interfacial Engineering, and Cutting‐Edge Applications

Aramid nanofibers (ANFs) combine exceptional mechanical robustness with nanoscale processability and a chemically accessible surface, making them attractive building blocks for multifunctional composites. However, the limited intrinsic functionality of pristine ANFs restricts their broader use in electronics and energy systems. Hybridization with inorganic nanomaterials provides an effective strategy to integrate mechanical resilience with diverse functional properties. Distinct from previous reviews organized by preparation methods or applications, this review establishes an interface‐structure‐transport‐function framework for ANFs/inorganic nanocomposites. Interfacial engineering strategies, including noncovalent interactions, covalent coupling, coordination, biomimetic adhesion, surface functionalization, and in situ growth are systematically analyzed for their effects on stress transfer, charge/phonon/ion transport, and electromagnetic attenuation. Advances in ANFs preparation and composite fabrication are correlated with applications in electromagnetic interference shielding, wave absorption, thermal management, and electrochemical energy storage. Particular focus is given to structure and property relationships in the context of specific applications, along with performance bottlenecks and manufacturing constraints. Finally, perspectives on greener processing, programmable interfacial assembly, hierarchical design, and scalable manufacturing are discussed. By connecting interfacial chemistry with transport mechanisms, functional performance, and manufacturability, this review offers transferable design principles for next‐generation ANFs/inorganic multifunctional nanocomposites.
