The analytical methods of DSC and Raman microscopy have been combined to provide direct evidence of a sequential cure mechanism, whereby the siloxane network forms before a methacrylate-functional adhesion promoter is cured into the matrix. Surface compositional profiles by ATR-IR microscopy and XPS have provided direct evidence of AP enrichment at interfaces in an addition cured silicone matrix. The resulting understanding can be exploited to develop systems with tailored interfaces for in-situ surface modification and control of a range of interface-dependent properties such as adhesion or release.
