A novel bio-template strategy of assembled silver nanowires with cluster-random structure via tomato epidermis for transparent electromagnetic interference shielding and joule heating
Transparent conductors (TCs) are applied in electromagnetic interference shielding and transparent electronic heaters due to their superior optoelectronic performance. Herein, a bio-template-based self-assembly strategy for silver nanowires (AgNWs) is employed to create novel “island-like” AgNW cluster morphologies, distinguishing from traditional random or circular shapes of AgNWs on PEN substrate. The unique structure ensures multidimensional pathways for free electron migration while concentrating visible light channels. Utilizing ultrasonic spray coating, AgNW random networks cover the clusters, bridge inter-cluster gaps, and ensure outstanding optoelectronic performance. Employing patterned self-assembled AgNWs combined with random networks marks a pioneering approach to achieving precise tunable electromagnetic interference shielding efficiency (EMI SE) in the X-band and optical transmittance, accommodating the diverse needs of various environments. The composite structure, featuring bottomed AgNW clusters and topped AgNW random networks (CRS), displays high transmittance with single-layer coating, achieving a remarkable figure of merit (FoM) of 15,481 (T@550 nm = 99.90%, Rs = 25.26 Ω/sq). This configuration also provides EMI shielding of 20.04 dB in the X-band, meeting commercial standards. Additional layers enhance the CRS films’ optoelectronic stability accompanied by tunable EMI shielding and excellent Joule heating 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.
