Synthesis and Characterization of Carbon Nanotubes from Natural Source - Camphor Oil

摘要

Carbon nanotubes (CNTs) were deposited on silicon wafer (Si) by Thermal Chemical Vapor Deposition (TCVD). The new starting material of camphor oil was used as carbon precursor. The gas flow of Argon (Ar) was constant at 100 bubbles per minute and 30 minutes of deposition time. Before the deposition process, silicon was coated with mixture of nickel (II) nitrate hexahydrate, Ni (NO_3)_2·6H_2O and ethyl alcohol, C_2H_5OH using spin coater. Variable parameter which is deposition temperature has been studied. Chemical functional groups of carbon nanotubes were characterized using FTIR while surface morphology and uniformity were characterized using FESEM. The FTIR result shows peaks attributed to multi-walled carbon nanotubes (MWCNT) vibration modes.
