Figure Lengend Snippet: a) SEM and EDS image showing the morphology of the pure hBN sample revealing the chemical composition of a Si wafer. b) SEM and EDS results for hBN (m) nanosheets, confirming the attachment of iron oxide. c) and d) FTIR and Raman spectra of hBN and hBN (m) . e) Magnetization hysteresis loop at room temperature, illustrating the magnetic characteristics of the investigated materials. The inset of (e) highlights the separation behavior of hBN (m) in deionized (DI) water when exposed to an external magnetic field. f) show the XPS spectra of hBN and hBN (m) . The inset of (f) highlights the Fe 2p peak, confirming the successful doping of iron oxide on hBN to form hBN (m) nanosheets. g) and h) show the XPS spectra of the O 1s and N 1s peaks of hBN (m) . i) Raman spectra of pure PDMS and PDMS@hBN (m) composites, highlighting the structural differences.

Article Snippet: To initiate the synthesis of magnetically responsive hBN nanosheets, Hexagonal boron nitride (hBN) nanosheets (density of 2.5 g cm −3 ) with a purity of 99.7% and an average size of 300 nm, procured from Nanografi Nano Technology in Turkey, was chosen as the primary material.
