摘要：

By immersing copper in a water dispersion of the Organic Metal (OM) polyaniline (PAni) a thin layer is adsorbed at the surface forming a Cu(I)-PAni complex. XPS analysis showed only Cu(I) signals. Upon aging, the PAni treated Cu surface shows an exponentially decreasing Cu2O layer, and an increase of CuO with roott. An acid etched Cu surface shows a linear increase of both Cu2O and CuO. The PAni treatment passivates Cu. The role of polyaniline in the passivation process of copper is discussed and kinetic data are presented.
