The project addresses the antifouling properties of polymeric surfaces, in particular of zwitterionic ones, in aqueous environments. Novel zwitterionic polymer architectures will thus be designed, synthesized, and investigated with respect to their non-fouling properties. Therefore, zwitterionic polymers will be synthesized and characterized regarding their non-fouling properties. We will focus on highly crosslinked and weakly amphiphilic polysulfobetaines and – carboxybetaines. By this, the previously observed susceptibility against silt uptake while maintaining the ultralow-fouling properties in laboratory assays will be reduced. Also, the hitherto realized zwitterionic structures will be further extended. Systematically varied series of polymers will allow to reveal fundamental relationships between the structure of the polymers and their antifouling and anti-sediment properties.

该项目涉及聚合物表面，特别是两性离子表面在水环境中的可降解性。因此，新型两性离子聚合物结构将被设计、合成和研究其不结垢性能。因此，将合成两性离子聚合物并表征其不结垢性质。我们将集中在高度交联和弱两亲性聚磺基甜菜碱和-羧基甜菜碱。通过这种方式，将减少先前观察到的对淤泥吸收的敏感性，同时保持实验室测定中的超低结垢特性。此外，迄今实现的两性离子结构将进一步扩展。系统地改变聚合物的系列将允许揭示聚合物的结构与它们的抗水和抗沉淀性能之间的基本关系。
