| Abstract: | Carbon nanofibers (CNFs) were electrodeposited on indium tin oxide (ITO) electrodes by using a DC electric field from N,N′-dimethylformamide (DMF). An improved dispersion of CNFs has been found in DMF solution compared to ethanol and acetonenitrile. After treated by concentrated H2SO4/HNO3, CNFs were dispersed uniformly and stably in DMF. During the electrodeposition process, CNFs moved towards anode indicating the negative charge of the nanofibers. Effects of electric field strength, CNF concentration in the suspension, and the solvents used for CNF dispersion were examined on the deposition nature of CNFs. |
