Influence of interface chemistry and network density

研究领域：涂层涂料腐蚀 交流阻抗频率范围：100kHz - 1Hz n-Butyl acrylate/styrene copolymer films were applied on iron and zinc surfaces. The kinetics of interfacial ion transport and cathodic delamination were tracked by in situ Scanning Kelvin Probe (SKP) measurements.A destabilisation of the interface was detected for latex network structures with an increased degree of cross-linking. In contrast, a reduction of the average macromolecular chain length resulted in films with higher resistance to interfacial ion transport.
