A critical review of hexagonal boron nitride manufacturing technology for electronics cooling applications

Paper i proceeding, 2024

This study reviews the latest advances in hexagonal boron nitride stripping technology, including various exfoliation methods. The advantages, disadvantages and principles of these techniques are analyzed, in addition to the influencing factors, in order to provide a comprehensive understanding of the latest technologies for future research directions in hexagonal boron nitride. It was shown that the choice of stripping agent directly affects the stripping results, and during the stripping process, temperature, pressure and stripping speed, the stripping conditions have a great influence on the structure and properties of the crystals. It was also found that physical properties such as thickness, surface roughness and crystalline quality of the exfoliated flakes are important factors affecting the thickness of the final h-BN layer, and that these parameters directly influence the thermal and mechanical properties of the material, as well as its stability and reliability in equipment applications. The dispersion, morphology and size distribution of the dispersions were also found to be key parameters affecting cluster formation and thermal properties. These parameters affect the homogeneity and enhancement of the dispersions in the material, which directly affects the performance of the final formulation. We have also focused on the chemical properties of the exfoliated sheets and dispersions, such as surface chemistry and surface energy. These properties not only affect the interfacial compatibility and adhesion of the material, but also have a significant impact on its stability and reactivity in a given environment.
