碳纳米管中的准高压效应及其应用

Quasi-high pressure effects in carbon nanotubes and its application

碳纳米管是具有中空管结构的新型纳米碳素材料,其直径一般在1nm至数10nm之间。详细论证了碳纳米管中存在的准高压效应,研究表明该压强超过了1.9GPa,而在电子辐射的作用下更可能高达40GPa,可以起到诱导填充物相变与化学反应以及调控自身和填充物电子状态的作用。同时,还介绍了该准高压效应在储气等方面的应用,并指出目前存在的问题以及展望了未来的发展。

Carbon nanotubes are novel carbon nano-materials with hollow structure,the diameters of which are usually in the range of lnm to several tens of nanometers,A comprehensive review of the quasi-high pressure effects in carbon nanotubes were summarized. The internal pressure inside nanotubes might reach values higher than 1.9 gigapascals,and up to 40 gigapascals under electron irradiation, which could induce phase transition and chemical reaction and regulated electronic states of filler and itself. The applications of quasihigh pressure effects were also introduced, such as gas storage, In addition, some problems and future developments were presented.
