Boron nitride nanotubes are an emerging class of inorganic nanotubes with insulating property, exceptional thermal stability, high thermal conductivity, and superior mechanical properties including ultrahigh strength and elastic modulus which are not possible in conventional materials. This project aims to apply state-of-the-art in-situ transmission electron microscopy techniques to explore the dependence of mechanical properties on size, morphology and structure of boron nitride nanotubes and the effect of mechanical strain on electrical properties, which will provide opportunities for composite materials reinforcement via nanotubes, and tune the electronic and optoelectronic properties of nanotubes via strain engineering.

氮化硼纳米管是一种新兴的无机纳米管，具有绝缘性能、优异的热稳定性、高导热性和卓越的机械性能，包括超高强度和弹性模量，这些都是传统材料所不具备的。本项目旨在应用最先进的原位透射电镜技术，探索氮化硼纳米管的力学性能对尺寸、形貌和结构的依赖关系，以及机械应变对电学性能的影响，为通过纳米管增强复合材料提供机会，并通过应变工程调整纳米管的电子和光电子性能。
