New Zwitterionic Polymers "Low-fouling" Surfaces

该项目致力于聚合物表面，特别是两性离子表面在水环境中的防污性能。因此，将设计、合成和研究新型两性离子聚合物的无污染性能。因此，将合成两性离子聚合物，并对其无污染性能进行表征。我们将集中于高交联性和弱两亲性的聚磺基甜菜碱和-羧基甜菜碱。这样，以前观察到的对泥沙吸收的敏感性将会降低，同时在实验室测试中保持超低污染特性。此外，迄今实现的两性离子结构还将得到进一步扩展。系统变化的聚合物系列将能够揭示聚合物结构与其防污染和防沉淀性之间的基本关系。

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.
