Intercalation of Nanoscale Multiferroic Spacers between the Two-Dimensional Interlayers of MXene.

We report a facile synthesis of MXene/bismuth ferrite (Ti3C2T x @ BiFeO3) nanocomposites using hydrazine hydrate induced with the hydrothermal method. Preparation of the composite with hydrazine hydrate prevents the formation of Bi25FeO39 inside the matrix. The 25 wt % loading of BiFeO3 acts as spacers for the multilayer restacking of MXene flakes by retaining the (002) plane. This promotes large dc conductivity with interfacial and defect dipole polarization mechanisms inside the composite material. The thinner M-H loop also indicates the minimal magnetic loss inside the composites. The facile synthesis strategy provides outstanding properties in Ti3C2T x @ BiFeO3 composites as two-dimensional multiferroic materials.
