摘要：
Structural evolution of electrospun poly(acrylonitrile) based carbon fibers embedded with multi-wall carbon nanotube (MWCNT) by heat treatment between 1000 and 3000 degrees C is reported. The graphitization of the fibers is seen to be enhanced in the presence of MWCNT. Graphite fibers with high crystallinity and with a lattice constant nearly equal to that of highly oriented pyrolytic graphite can be prepared at a temperature of 2000 degrees C, with a small percentage (similar to 5 wt.%) of MWCNT embedded into it. This is a reduction of the graphitization temperature by similar to 1000 degrees C from the conventional graphitization temperature of similar to 3000 degrees C without the addition of any metallic catalyst.
