XPS was employed to confirm the presence of B and N elements, while optical properties were analyzed using UV-Vis-NIR spectroscopy and Raman spectroscopy. Additionally, it also includes schematic diagrams of the synthesis process of hBN on copper foil, the thermal oxidation testing procedure, and the PMMA-assisted method
