Boron Nitride Nanosheets: novel Syntheses and Applications in polymeric Composites

Abstract. Two-dimensional (2D) boron nitride (BN) nanosheets, the rising material stars, have\ud unique properties and amazing functionalities. The concise history of diverse synthesis routes\ud of BN nanosheets is briefly summarized here; and the recent development towards mass\ud production of BN nanosheets, i.e. “chemical blowing” technique relying on blowing molten\ud polymer precursors into large polymeric bubbles and subsequent annealing into BN\ud bubbles/nanosheets, is focused on. The abundant BN nanosheets enable their applications,\ud especially in the representative polymeric composites with BN nanosheet additives, as\ud particularly highlighted in this review. The highly thermoconductive insulating BN-filled\ud composites are thus envisaged as high-performance packaging materials for electrical circuits
