Figure 1. (A) Schematic illustration of the customized fabrication route; (B) Hydroxyl functionalization process of BSZMT-NPs and h-BNNS; (C) XRD patterns of BSZMT ceramics, the inset showing diffraction peaks in the 44°-46°; (D) XRD patterns of nanocomposites with varying content, the inset showing peaks at ~31°; (E) SEM surface morphology and EDS of BSZMT ceramics, with the inset showing an average grain size; (F) SEM surface morphology and EDS of the 6@4BNNS nanocomposite; (G) SEM image of the hydroxyl-functionalized 6@4BNNS composite; (H) SEM image of the unfunctionalized 6@4BNNS composite surface. BSZMT: Ba_0.63Sr_0.37Zr_0.01(Ti_0.999Mn_0.001)_0.99O₃; NPs: nanoscale particles; BNNS: boron nitride nanosheets; XRD: X-ray diffraction; SEM: scanning electron microscopy; EDS: energy dispersive X-ray spectroscopy.
