polymers are paid much more attention for application in corrosion by many
scientists in the recent years. The protect mechanism are controversially
discussed, especially the reactions take place in the buried interface
metal-conducting polymer. In this paper, Kelvin Probe is introduced as a new
method to investigate the corrosion process as well the delamination of
conducting polymer polyaniline on metal. The effects of oxygen, the size of
cation in solution on the delamination of polymer film are discussed.
