Self-sacrificed template synthesis of ribbon-like hexagonal boron nitride nano-architectures and their improvement on mechanical and thermal properties of PHA polymer

Abstract Two-dimensional (2-D) boron nitride (BN) nanomaterials have received intensive attention because of their attractive mechanical, thermal and chemical stability. Here we demonstrate, for the first time, the synthesis of ribbon-like hexagonal boron nitride nano-architectures (RLBN) through a...
