【 摘 要 】

Methods that facilitate exfoliation of hexagonal boron nitride (hBN), exfoliated hBN, and associated intermediate products are disclosed. Such a method can include the acts of mixing a sample of hBN with an activation agent (e.g., NaF, etc.) and a selected set of chemicals (e.g., a metal chloride) and intercalating the set of chemicals into the hBN to obtain intercalated hBN. Additionally, such a method can include the acts of hydrating the set of chemicals (i.e., the intercalates), and converting the set of chemicals to a set of oxide nanoparticles when exfoliating the intercalated hBN. The exfoliated hBN can be washed (e.g., with HCl, etc.) to remove remaining nanoparticles.
