The transport of metal ions along the polymer/steel
interface is believed to be the controlling factor in
the cathodic delamination of polymer-coated steel
exposed to electrolytes. In situ measurement of metal
ions at the polymer/substrate interface would provide
critical information for understanding and modeling the
delamination rate of this material. A number of
techniques can be used for measuring metal ions on solid
surface or in solution. However, most of these
techniques are not suitable for in situ investigation at
the buried polymer/substrate interface. Infrared (IR)
spectroscopy in the internal reflection mode on a
suitable substrate is attractive for such study because
it probes the interface from the substrate side and can
be used at ambient conditions.
