| Abstract | ||
|
The design of long-term stable and corrosion resistant polymer/oxide/metal interfaces can be based on the interfacial analysis of the chemical, electrochemical and microscopic structure. Mainly in-situ analytical studies are of interest to reveal the mechanisms of adhesion and de-adhesion under ambient conditions. Highlighted techniques will be FTIR- and Raman spectroelectrochemistry, Chemical Force Microscopy and the Scanning Kelvin Probe technique. These methods can be combined with applied computational chemistry which helps to analyze interfacial chemical bonds and adsorption processes mainly on single crystalline oxide surfaces. Systems under investigation are organosilanes and organophosphonic acids as molecular adhesion promoters on zinc and aluminium oxides. The thereby generated knowledge serves as basis for the design of highly corrosion resistant organic coatings and adhesives on zinc, aluminum or steel substrates. The presentation gives an overview about the corresponding recent research and tries to bridge the gap between the theoretical aspects of interface chemistry and the technically relevant surface chemistry. |
