This study intends to elucidate how molecular hairy or brush-like structures form on different flat surfaces. When molecule chains form a densely packed assembly on a surface they are called 'brushes' or 'polymer brushes'. These types of structures can afford surface properties such as low surface friction or the ability to prevent bacteria from sticking to the surface. The polymer brushes we want to study form by segregating out from the underlying bulk material into water. Bulk material such as rubber silicone or polyurethane act as a resevoir from where the polymer brushes can segregate. This process happens spontaneously in the right solvent conditions and high enough content of polymer brush chains filled into the silicone. We would like to further understand the segregation process for e.g. industrial applications such as biomedical surface coatings or non-fouling ship hull paints.
