EN Impedance spectroscopy has been applied as potentially non-destructive method for the evaluation of adhesion at the interface between two polymer layers in protective coating system. The aim was to examine the effect of the outdoor humidity on the interfacial impedance. Aautomotive basecoat/clearcoat system has been investigated.Anew electrode sensor has been employed to detect the changes caused by adhesive debonding and accumulation of water at the interface. The electrode comprising two thin stripes of an electroconductive ink was placed between two coating layers. Large changes in the impedance were observed when humidity conditions were altered. The obtained data were indicative for strong sensitivity of the interlayer impedance to the outdoor humidity.Water accumulation in the interlayer and the formation of conductive paths led to the worsening of adhesion and deamination of the coating layers.
