Abstract

Carbon nanotubes and polyvinyl alcohol (CNTs/PVA) nanocomposite were prepared by using sol-gel method and thin film was prepared by using spin coating technique on mild steel substrate. Sol-gel is a convenient technique used for the production of nanocomposite aqueous solution and spin coating is a simple method that is widely used for producing a very thin organic thin film. Five samples were prepared at the different concentration of CNTs/PVA to verify the corrosion rate application. The samples were then characterized by Field Emission Scanning Electron Microscopy (FESEM) and Atomic Force Microscopy (AFM) obtaining the structural properties, surface morphology and topography of samples. Raman spectroscopy was used to determine the microraman spectra of CNTs which showed the crystalinity and purity of samples. Finally, corrosion test was done to measure the corrosion rate of samples at the different concentration of CNTs/PVA nanocomposite. Based on the work, sample with 0.03g CNTs likely the optimum sample which suitable for coating application.
