First Time

MXene, the new family of two-dimensional materials having numerous nanoscale layers, is being considered as a novel microwave absorption material. However, MXene/functionalized MXene-loaded polymer nanocomposites exhibit narrow reflection loss (RL) bandwidth (RL less than or equal to −10 dB). In order to enhance the microwave absorption bandwidth of MXene hybrid-matrix materials, for the first time, macroscopic design approach is carried out for TiO 2 -Ti 3 C 2 T x MXene and Fe 3 O 4 @TiO 2 -Ti 3 C 2 T x MXene hybrids through simulation. The simulated results indicate that use of pyramidal meta structure of MXene can significantly tune the RL bandwidth. For optimized MXene hybrid-matrix materials pyramid pattern, the bandwidth enhances to 3–18 GHz. Experimental RL value well matched with the simulated RL. On the other hand, the optimized Fe 3 O 4 @TiO 2 -Ti 3 C 2 T x hybrid exhibits two specific absorption bandwidths (minimum RL value - −47 dB). Compared with other two-dimensional nanocomposites such as graphene or Fe 3 O 4 -graphene, MXene hybrid-matrix materials show better microwave absorption bandwidth in macroscopic pattern.

Layered Perovskites

Layered perovskites have attracted considerable attention in optoelectronic applications due to their excellent electronic properties and stability. In this work, the quasi-2D aurivillius halide perovskites are investigated using density functional theory. The single-layer aurivillius perovskite Ba2PbI6 is predicted to have a direct bandgap of 1.89 eV, which is close to that of the Ruddlesden–Popper perovskite Cs2PbI4. The electronic structures near the Fermi level are mainly governed by the [PbX6] octahedra, which leads to similar electronic properties to that of Cs2PbI4. Decomposition energies reveal that these aurivillius perovskites exhibit thermal instability. Increasing the number of [PbX6] octahedra layer can enhance the stability and reduce the bandgap. Bi- and In-based aurivillius perovskites are also calculated to evaluate the Pb-free alternatives. These calculations can serve as a theoretical support in exploring novel layered perovskites.<br>
