Synthesis and Characterization of Multi-Branched Carbon Fibers and Their Proposed Growth Mechanism

In this study, carbon fibers with different morphologies in their initial growth period have been obtained by the chemical vapor deposition using nano-copper particles as a catalyst at 250 degrees C and then we have investigated the formation mechanism of the carbon fibers. Otherwise, we have noted that multi-branched carbon fibers with different morphologies were synthesized, and proposed the growth models for carbon fibers. X-ray diffraction, field emission scanning electron microscopy, transmission electron microscope, energy-dispersive x-ray were used to characterize the products.
