The development of advanced thermal transport materials is a global challenge. Two-dimensional nanomaterials have been demonstrated as promising candidates for management applications. Here, we report boron nitride (BN) nanosheet/polymer composite film with excellent flexibility and toughness prepared by vacuum-assisted filtration. mechanical performance the highly flexible robust. It noteworthy that exhibits anisotropic properties, superior in-plane conductivity around 200 W m-1 K-1 extremely low through-plane 1.0 K-1, making this material an candidate in electronics. Importantly, shows fire-resistant properties. newly developed unconventional flexible, tough, refractory BN films are also heat dissipation variety
