Preparation and Characterization of Carbon Nanotubes using Carbon Black by Electrochemical Technique with Anodic Aluminium Oxide
This study describes preparation and characterization of carbon nanotubes (CNTs) by anodic aluminium oxide (AAO) template assisted electrochemical deposition. A highly ordered array of cylindrical designed pores of anodic aluminium oxide was obtained from anodizing aluminum to use it as a template for deposition of carbon nanotubes. The fabrication of carbon nanotubes was done using moraine of micrometer sized carbon black with diameter range of 0.5-75 μm. The characterization of carbon
... n of carbon nanotubes was done by FTIR, SEM and AFM indicating the formation of carbon nanotubes within anodic aluminium oxide template by electrodeposition at room temperature. FTIR spectrum indicated the presence of peaks of CHx group associated with O-H, in addition to appear COOH group after functionalization of carbon nanotubes with (HNO3-H2SO4) mixture to obtain functionalized carbon nanotubes (F-CNTs). The SEM morphology confirmed the fabrication of nanotube by appearing opened ends of tubes with nano dimensions. The atomic force microscopy analysis gave smother surface with more average diameters from 66.3 to 77.21 nm for F-CNTs compared with carbon nanotubes due to formation carboxylic groups.
