Impact of carbon nanotube derived from rice husk to improved Corrosion Resistance of Zinc-PVDF- coating on mild steel
Year: 2024
Type: article
Abstract: A carbon nanotube (CNTs) derived from rice husk was used in this work to reduce the unbound volumes and corrosion rate of Zn-PVDF in simulated sea water. The coating was developed using the electrodeposition method by varying CNTs from 0 to 0.6 g/L. Electrochemical impedance spectroscopy (EIS) determined the corrosion of the samples, while scanning electron microscopy determined the microstructure of the coated samples. The work shows that the addition of carbon nanotubes (CNTs) to Zn-PVDF significantly enhanced the overall corrosion resistance of the samples. The sample with a 0.6 g/L coating demonstrated the greatest corrosion resistance, with 309.19% corrosion protection efficiency. The microstructure demonstrated that adding CNTs reduced PVDF volume expansion. The study has demonstrated the use of waste rice husk in the production of carbon nanotubes to enhance the corrosion resistance of Zn PVDF coatings.
