Pressure sensitive adhesives (PSAs) are widely used in everyday applications, industries and medicine. Individually tailored compounds exist for many fields of application. Among these is the establishment of strong but reversible adhesive bonds between metal surfaces. The interactions between a metal adherent and the polymeric adhesive govern the performance of any metal-adhesive joint and are therefore important to understand. We present an in-situ grazing incidence small angle X-ray scattering (GISAXS) study on the growth of metal films sputtered on a model PSA as well as on its homopolymer components. Different growth kinetics reveal insights into the metal-polymer interactions and isolate the influence of atomic and molecular forces due to the absence of usual adherent surface properties like its roughness or preceding surface treatments, e.g. cleaning. GISAXS provides means to follow the metal film formation during sputtering in-situ, revealing structural information with a very high time resolution.
