Abstract

All electronic devices are susceptible to electromagnetic interference (EMI) phenomena, and EMI shielding is necessary to mitigate this issue and ensure the safety and efficiency of electronic components. In this research work, we vali datedthehypothesisthattheintegrationoftwo-dimensional(2D)materialsofMXene andalignedcobaltnanowires(CoNWs)intoCNTbuckypaperssignificantlyenhances their electromagneticinterferenceshieldingeffectiveness(SE).TheTi3C2Tx MXene/ CNTbuckypaper displayed an impressive EMI SE of 94.2 dB. The EMI SE is main tained consistently across the tested frequency range of 8.4–12.0 GHz. Furthermore, Ti3C2Tx MXene/CoNW/CNT buckypaper, incorporating a three-layered composite structure, showed an even more remarkable EMI SE of 137.4 dB. Such 2D layers of MXene with aligned CoNWs not only contribute to the physical robustness of the buckypaper but also introduce magnetic losses, which are instrumental in absorbing and thus shielding against electromagnetic waves.
