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

Abstract

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. © 2005 Elsevier B.V.
