Resumo
We report a facile synthesis of MXene/bismuth ferrite (Ti3C2Tx @
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
Ti3C2Tx @ BiFeO3 composites as two-dimensional multiferroic materials.
