The Marangoni effect is a phenomenon describing fluids flow from regions of low surface energy to regions of high surface energy. In thin polymer films, this effect could offer a practically useful route to manufacture patterned surfaces. Previous research has shown that the mixing a photosensitizing compound with polymer enables significant increases in feature aspect ratio and expands the applicability of the Marangoni patterning method to more readily available light sources and other classes of polymers. In this poster presentation, we will present a way to further optimize/maximize the feature aspect ratio of the Marangoni-driven patterns using a 9, 10-dibromoanthracene and polystyrene thin film model system. To highlight versatility of our patterning method, the patterned polymer film was used for cell alignment. |
