Researchers use scanning electron microscopy (SEM) to characterize a lightweight, flexible material with high performance shielding capabilities
From wearable fitness trackers, such as smartwatches, to wearable healthcare devices, such as ECG and blood pressure monitors, there is a rising demand for increasingly advanced wearable devices. Devices such as these are packed with highly integrated circuits, which generate electromagnetic radiation. As such, there is a need for high performance, electromagnetic interference (EMI) shielding materials that are both lightweight and flexible.
Dr. Yongwen Tan and his research group at Hunan University, China, have published an article presenting a method for fabricating light-weight, foldable, and highly stable MXene foams. MXene foams are 2D transition metal carbides and/or nitrides with metallic conductivity that have shown promise for EMI shielding. Dr. Tan provided us with some insights into his publication and use of scanning electron microscopy (SEM) for characterization of these foams.
