1. An electronic device, comprising:
an antenna-comprising portion, the antenna-comprising portion including therein or thereon an antenna comprising a MXene composition that comprises:
(a) at least one layer having first and second surfaces, each layer described by a formula Mn+1XnTx and comprising:
substantially two-dimensional array of crystal cells, each crystal cell having an empirical formula of Mn+1Xn, such that
each X is positioned within an octahedral array of M, wherein
M is at least one Group IIIB, IVB, VB, or VIB metal, wherein
each X is C, N, or a combination thereof;
n=1, 2, or 3; and wherein
Tx represents surface termination groups; or
(b) at least one layer having first and second surfaces, each layer comprising:
a substantially two-dimensional array of crystal cells,
each crystal cell having an empirical formula of M′2M″nXn+1Tx, such that each X is positioned within an octahedral array of M′ and M″, and where M″n are present as individual two-dimensional array of atoms intercalated between a pair of two-dimensional arrays of M′ atoms,
wherein M′ and M″ are different Group IIIB, IVB, VB, or VIB metals,
wherein each X is C, N, or a combination thereof;
n=1 or 2; and wherein
Tx represents surface termination groups.
