Combinatorial Materials Science for Polymer Thin-Film Dewetting



J C. Meredith, A P. Smith, Alamgir Karim, Eric J. Amis


A combinatorial technique is described for rapid measurement of phenomena associated with thin-film polymer science. Thin-film libraries of polystyrene on silicon, containing systematic variations in film thickness and temperature, are prepared with a velocity-gradient film coater and subjected to a temperature gradient. Libraries are screened for dewetting behavior with automated optical microscopy and image analysis. The high-throughput physical characterization method is validated by comparison to conventional studies and a comprehensive dewetting phase-map is generated. The method also reveals novel observations of film stability and kinetic transitions as well as the time-temperature-thickness superposition for metastable dewetting kinetics.
