The Effect of Inoculum in the Preparation of Fermented Tapioca for Nanotechnology Applications Based on the Surface Morphology of CNTs

Abstract:

Fermented tapioca which is a new starting material was used as a carbon precursor. Carbon nanotubes (CNTs) were deposited on silicon wafer (Si) by Thermal Chemical Vapor Deposition (TCVD). The gas flow of Argon (Ar) was constant at 70 bubbles per minute and 20 minutes of deposition time. Before the deposition process, silicon was coated with Nickel using spin coater. Various parameters such as amount of inoculums have been studied. Surface morphology and uniformity were characterized using FESEM. The surface morphology and uniformity of CNTs are dependents on parameters used. The optimum CNTs that produced using Thermal CVD was 1.5 wt% of inoculums due to the size and the uniformity of CNTs growth.
