Abstract
The corrosion protection of acrylate:carbon nanotubes (A:CNTs) nanocomposite thin film has been coated on mild steel characterised by electrochemical impedance spectrometer (EIS) measurement and equivalent circuit model are employed to analyse coating impedance for corrosion protection. In this study, 3.5 w/v% sodium chloride (NaCI) solution was used to immersed the A:CNTs nanocomposite thin film. From EIS measurement, A:CNTs nanocomposite thin film with 0.4 w/v% contain of CNTs was exhibited the highest coating impedance from Nyquist graph after immersed in NaCI solution and may provide the excellent corrosion protection.
