多壁碳纳米管的爆轰改性
Detonation Modification of Multi-Walled Carbon Nanotubes
摘要
Abstract
In order to study the influence of detonation reaction on the morphology and phase of multiwalled carbon nanotubes (MWCNTs),the mixed explosives,made from MWCNTs and RDX with a given mass ratio,were detonated in the reaction kettle.The samples before and after detonation were characterized using transmission electron microscopy and X-ray diffractometer.The results show that the mixed explosives can be detonated successfully when the mass ratio of MWCNTs ranged in 30%-40 %,and a large number of samples can be collected.Moreover,the morphology and phase of MWCNTs show great changes after detonation.The morphologies are transformed into sheet,rod and ball from tubular structure,accompanied with an obvious agglomerate phenomenon,and a small quantity of MWCNTs are located at the edge of the carbon sheet.The samples are mainly amorphous carbon.The degree of graphitization is much less than that of the original MWCNTs,and it increases as the mass ratio of MWCNTs increases in the mixed explosive.关键词
