摘      要：Corrosion protection of the hull steel by the conventional epoxy paint containing a small amount of commercial poly（3,4-ethylenedioxythiophene）/poly（styrene sulfonate） （PEDOT/PSS）, which is one of the most popular and successful inherently conducting polymers as the corrosion inhibitor was studied. The corrosion behavior of the samples was investigated in seawater by electrochemical impedance spectroscopy and open circuit potential. Scanning electron microscopy was used to observe the surface morphology of the samples after corrosion. It was found that adding a small amount of PEDOT/PSS to the epoxy resin can significantly improve its corrosion protection.
