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

We report a facile synthesis of MXene/bismuth ferrite (Ti₃C₂T @ 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 @ BiFeO₃ composites as two-dimensional multiferroic materials.
