The tremendous growth of wireless communication and smart nano-micro electronic devices has triggered electromagnetic interference (EMI) pollution in the environment. EMI is a significant problem concerning both animals and humankind. Various problems like data leakage, interferences from electronic devices and health hazards can be addressed with an efficient electromagnetic (EM) wave shielding material. In this chapter, a new research interest, 2D material, is studied to investigate their EMI shielding capacity. 2D MXene are transition metal carbides or nitrides obtained from the parent MAX phase resulting in orderly stacked layers. Better EMI shielding mechanism within 2D layers and enhanced absorption in various composites of MXene are summarized.
