Investigating the Effects of Synthesis Parameter on the Yield and Structural Health of In-Situ Grown Carbon Nanotubes
Carbon nanotubes have proved to be very unique and versatile reinforcing agent for the development of nanocomposites in recent times. In this study, CNTs were grown on cobalt based nano particles by Alcoholic Catalytic Chemical Vapor Deposition process for the fabrication and promotion of hard metallic in-situ nanocomposites materials. Alcoholic (ethanol) precursor was preferred as it minimizes defects on CNTs surfaces. Besides in-situ growth of CNTs, other main objective of this study was to optimize a reaction temperature (among several), which offered better yield and quality of grown CNTs. Yield and quality index of CNTs were better at 900ºC. Influence of synthesis reaction temperatures on quality of grown CNTs was investigated by Raman Spectroscopic technique. CNTs graphitic hexagonal crystal planes were confirmed by XRD spectra.
