5.5GPa下碳纳米管的热稳定性研究
DOI: 10.11858/gywlxb.1998.01.003, PP. 17-21
Keywords: 碳纳米管,高压,热稳定性
Abstract:
利用X射线衍射和透射电子显微镜研究了碳纳米管在5.5GPa下的热稳定性问题。根据以往的研究在常压真空条件下碳纳米管的热稳定性非常好，其结构在2800℃以下可能并不发生变化。实验中发现，虽然在5.5GPa压力下冷压作用后碳纳米管的微结构没有明显的改变，但在950℃既开始发生改变，转变成类巴基葱和类条带结构，而在1150℃其结构转变成石墨结构。高压是这种转变的主要原因，高压可以促使碳纳米管管结构的破裂，从而减小了它的热稳定性。
