Structure and mobility of surfactant additives in PDMS resin

Abstract: Polysiloxane materials are commonly used in marine coatings due to their inherently low surface energy and flexibility which makes them suitable base materials for foul release coatings. As part of a larger investigation into molecular migration in complex polymer matrices, we are addressing curable polymers as an interesting class of matrix in which mobility and miscibility are expected to change dramatically during curing. In this experiment, we want to better understand how surfactants assemble in such matrices, how this is altered by the curing process and how they can be leached out over time. We begin with a simple nonionic surfactant and propose to use SANS to study its self assembly in PDMS before and after curing, followed by an analysis of the leaching process by exposure to water.
