Abstract
Multifunctional carbon fiber (CF)–based composite membranes engineered for superior electromagnetic interference (EMI) shielding and advanced thermal management are fabricated by decorating wrinkled reduced graphene oxide (rGO) onto CF networks to form carbon nanofiber/rGO (CFG) composite membranes, followed by the assembly of a highly conductive silver nanowire (AgNW) layer. With a desired carbonization temperature and an asymmetric configuration design, the asymmetric hybrid carbonaceous membranes demonstrated a high electrical conductivity of 3900 S m−1 and achieved an enhanced EMI shielding effectiveness of up to 84.5 dB within the X-band frequency range, which is attributed to the special “absorption-reflection-reabsorption” EM wave shielding mechanism enabled by the AgNW reflection layer and the hybrid conductive network. Additionally, the membranes exhibit robust photothermal responses characterized by excellent cycling stability and tunability under light irradiation, owing to their light scattering and synergistic effects. Remarkably, the multifunctional membranes attain a rapid temperature increase, reaching 165 °C under a modest 5 V input. This work provides valuable insights and opens up new avenues for the development of high-performance, multifunctional CF-based membranes, holding great promise for applications in efficient EMI shielding and temperature management.
Graphical Abstract
The carbon fiber (CF)/reduced graphene oxide (rGO)/silver nanowire (AgNW) asymmetric hybrid carbonaceous CFG-Ag membranes were fabricated, and the as-obtained samples possessed excellent electromagnetic interference shielding and superior electro-photo-thermal performance.
期刊介绍：
Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field.
The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest.
Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials.
Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
