Aim of the project is the synthesis and investigation of doubly and orthogonally switchable block copolymers in volume and in thin film geometry. These consist of a zwitterionic and a thermoresponsive block. In dependence of the chemical nature of the two blocks and of the block lengths, the switching behavior upon changes of temperature and electrolyte concentration will be investigated, namely in aqueous solution and in thin film geometry. Both, the structures and the kinetics of their changes upon a jump over one of the phase boundaries will be characterized in solution and in thin film geometry using modern scattering methods and fluorescence correlation spectroscopy.

该项目的目的是在体积和薄膜几何形状的双重和正交切换嵌段共聚物的合成和调查。这些由两性离子和热敏性嵌段组成。在依赖的两个块的化学性质和块的长度，切换行为时的温度和电解质浓度的变化将被调查，即在水溶液中，并在薄膜的几何形状。这两个，结构和动力学的变化后，跨越一个相边界的跳跃将其特征在于在溶液中，并在薄膜的几何形状，使用现代散射方法和荧光相关光谱。
