Recent advancements in electromagnetic interference (EMI) shielding technology have emerged from a collaborative research effort led by Mariam Mansoori at the Department of Mechanical & Nuclear Engineering at Khalifa University of Science and Technology in Abu Dhabi. This research, published in ‘Composites Part C: Open Access’ (translated from French as ‘Composites Part C: Accès Ouvert’), showcases the development of innovative three-layered thin film composites designed to significantly enhance EMI shielding capabilities.
The multilayer composites consist of strategically engineered layers: the base layer utilizes multi-walled carbon nanotubes (MWCNT) combined with carboxymethylcellulose (CMC), the middle layer incorporates MWCNT/CMC with iron oxide (Fe3O4) particles, and the top layer is a sophisticated blend of MXene, MWCNT, CMC, and Fe3O4. This layered approach not only optimizes the electromagnetic properties of each component but also results in impressive performance metrics. The multilayer composite demonstrates an EMI shielding effectiveness (SET) of 48 dB, a shielding effectiveness for absorption (SEA) exceeding 33 dB, and a low shielding effectiveness for reflection (SER) of 15 dB in the X-band frequency range.
Mansoori emphasizes the significance of these findings, stating, “The multilayer architecture allows us to tailor the electromagnetic properties to meet specific shielding requirements, which is crucial for industries that rely on electronic devices.” This adaptability is particularly relevant in the construction sector, where the integration of advanced materials can mitigate the adverse effects of electromagnetic radiation on sensitive equipment and enhance the overall safety and functionality of buildings.
As urban environments become increasingly saturated with electronic devices, the demand for effective EMI shielding solutions is surging. The construction industry stands to benefit immensely from this research, as it paves the way for the incorporation of these advanced composites into building materials. This could lead to the development of structures that not only provide physical shelter but also protect against the invisible threats posed by electromagnetic interference.
The implications extend beyond just construction; they touch upon sectors like telecommunications, automotive, and aerospace, where EMI shielding is critical for operational efficiency. The ability to create lightweight, flexible, and effective shielding materials could revolutionize product designs and enhance the performance of electronic systems.
As the construction industry continues to evolve towards smarter and more integrated designs, the findings from Mansoori’s research could serve as a catalyst for innovation, pushing boundaries in material science and application.
