Inhibition of corrosion by poly(N-hexadecylaniline)/docosanol mixed Langmuir–Blodgett films on copper in sea water

Electrochemical and weight loss techniques have been used for investigation of inhibition of corrosion on copper metal by Langmuir–Blodgett (LB) films of poly(N-hexadecylaniline)/docosanol in sea water. LB films of poly(N-hexadecylaniline)/docosanol were deposited onto the copper specimens. The open-circuit potential and potentiodynamic polarization curves were observed to shift in noble direction, which indicated that these LB films could inhibit the corrosion of copper metal in sea water.
