Abstract: Recent advances in two-dimensional (2D) nanomaterials have generated great interest in the investigations of these materials for wide ranging applications in the micro- to nano-scale electronics, healthcare, and energy storage areas. In particular, 2D materials such as boron nitride nanosheets (BNNS) have been studied extensively due to their unique material properties that include a large specific surface area, high thermal conductivity (~750 W/mK), and wide bandgap (~5.5 eV), along with the associated electrical insulation. In this paper, we prepared BNNS by liquid exfoliation of hexagonal boron nitride (h-BN). Liquid exfoliation is an enhanced method to achieve large-scale and low-cost production, which is more suitable for large volume applications. In this paper, we have combined low-energy ball milling and sonication methods to produce BNNS on a large scale.
