Tóm tắt

Synthesis temperature is one of important factors influencing on characteristics of carbon nanostructured materials. In this article, the authors evaluate the change of properties of nano composite C-CNFs obtained by simultaneously synthesizing and decorating NFs on the surface of the carbon felt at different temperatures. The results have shown that the carbon yield increases from 5.55 %wt to 227.13 %wt by enhancing the growth temperature from 620 oC to 680 oC. The results from Raman spectrum analysis have indicated that when the temperature rises from 620 oC to 680 oC, the ID/IG ratio decreases from 0.932 to 0.728. The decrease of ID/IG ratio has affirmed the increase in the graphitization degree of the product. However, this ratio increases slightly to 0.749 when the temperature is at 710 oC. This result demonstrate formation of amorphous carbon at high temperature. Besides, the obtained C-CNFs are also analyzed by several techniques such as SEM, TEM, TGA and BET.
