摘要: Self-assembled (SA) films of Schiff base were prepared on the copper surface. The corrosion protection abilities SA in chloride solution evaluated using electrochemical impedance spectroscopy and polarization curves. A subsequent adsorption 1-dodecanethiol original improved significantly ability to substrate. behavior surface was probed by X-ray photoelectron spectroscopy. It found that exists mainly Cu(I) state base, thiol molecules subsequently adsorbed bonded directly rather than physisorbed previous films. (C) 2002 Elsevier Science Ltd. All rights reserved.
