Abstract

An electromagnetic shielding material that includes a plurality of layers, each layer having a crystal lattice represented by: Mn+1Xn (wherein M is at least one metal of Group 3, 4, 5, 6, or 7; X is a carbon atom, a nitrogen atom, or a combination thereof; and n is 1, 2, or 3), each X is positioned within an octahedral array of M, and at least one of two opposing surfaces of said each layer has at least one modifier or terminal T selected from a hydroxy group, a fluorine atom, an oxygen atom, and a hydrogen atom; and dielectric and/or magnetic nanoparticles carried on a layer surface and/or between two adjacent layers of the plurality of layers.
