Polymer composites of boron nitride nanotubes and nanosheets

Hexagonal boron nitride (h-BN) is a layered material with planar networks of BN hexagons, which is flexible to form various nanostructures. This feature article begins with an overall introduction of BN nanostructures and their novel properties, such as electrical insulating properties, high thermal conductivity, great mechanical strength, optical properties, and so on. Then a comprehensive review of polymer composites of BN nanostructures with distinguished properties for different applications is presented. Finally, the problems of using BN nanostructures for the fabrication of polymer composites are discussed.
