Rapid Ferroelectric-Photoexcited Bacteria-Killing of Bi₄Ti₃O₁₂/Ti₃C₂T _x Nanofiber Membranes.

ABSTRACT: In this study, an antibacterial nanofiber membrane [polyvinylidene fluoride/Bi₄Ti₃O₁₂/Ti₃C₂T _x (PVDF/BTO/Ti₃C₂T _x )] is fabricated using an electrostatic spinning process, in which the self-assembled BTO/Ti₃C₂T _x heterojunction is incorporated into the PVDF matrix. Benefiting from the internal electric field induced by the spontaneously ferroelectric polarization of BTO, the photoexcited electrons and holes are driven to move in the opposite direction inside BTO, and the electrons are transferred to Ti₃C₂T _x across the Schottky interface. Thus, directed charge separation and transfer are realized thr
