Surface functionalization and exfoliation of hBN nanopowders by oxidation and SDS treatment

Key Points

• Exfoliation of hBN nanopowders increases significantly with sodium dodecyl sulfate and oxidation treatment.
• Results show that the optimal parameters lead to improved surface properties and dispersibility of the nanopowders.
• Observational analysis demonstrates the interaction of oxidation and surfactants to enhance exfoliation efficiency.
• This work highlights potential applications in electronic materials, though larger-scale studies are needed.
