Electrochemical behaviour of polyaniline–polyurethane (PANi–PU) antifouling thick coating (∼1 mm) over a corrosion resistant aluminium alloy in 3.5 wt% NaCl, is studied by electrochemical impedance spectroscopy (EIS).
- class="label">•
The effect of change of PANi content on the electrochemical behaviour of PANi–PU coating is studied and compared with neat PU.
