Electron microscopic studies on disintegration of core/shell polymer structure during heat treatment process in carbon nanotube preparation by polymer blend technique

Abstract

Carbon nanotubes CNTs 1 have attracted the attention of researchers to a considerable extent owing to their peculiar structures and possible applications in various fields, such as electronics, and also as nanocomposites and catalyst supports. These materials have been prepared by arc discharge 2 , laser ablation 3 , 4 , catalytic CVD CCVD 5 , and template methods 6 . The CCVD method is recognized
