Description
Hexagonal boron nitride (hBN) has emerged as a promising material for various application due to its unique properties, such as high thermal conductivity, electrical insulation, and mechanical strength. Recent advancements in the exfoliation of hBN into nanosheets through liquid-phase exfoliation have opened new opportunities for enhancing heat transport in various systems. This process involves the dispersion of bulk hBN in a solvent, leading to the formation of nanosheets with high surface areas and excellent thermal properties. The high in-plane thermal conductivity of exfoliated hBN enables efficient heat dissipation, essential for improving the performance and longevity of electronic devices. Few-layer 2D-hBN nanosheets are particularly attractive for the use in heat management solutions, including interface material, composites, coating for electronics, energy systems, and advanced materials. Our study demonstrates an effective approach for synthesizing 2D-hBN nanosheets in an environmentally friendly solvent, achieving a high aspect ratio. These nanosheets have potential applications as heat spreaders in electronic devices.
