The project focuses on synthesis of functionalized ionic liquids bearing one or two polymerizable functional groups, their polymerization, investigation of both the ionic liquids and the polymers made of them by broad-band dielectric spectroscopy, and investigation of applicability of these polymers as membranes for both gas separation and fuel cells. Homopolymers with either cationic or anionic segments and copolymers with both cationic and anionic segments as well as crosslinked ionic polymers are synthesized and characterized using spectroscopic and thermoanalytical methods. Thermal and UV-Vis induced polymerizations are used for polymer synthesis. Dynamics of the polymer chains and their interaction with gas molecules are highly important for application of the polymers as gas separating membranes. Furthermore, mobility and conductivity investigations on the polymers focus on their application as membranes for fuel cells. The properties of the polymers made and the results obtained by broad-band dielectric spectroscopy are the basis for polymer selection for application tests. Furthermore, results obtained during the application tests are a mutual basis for synthesis of further polymers.

该项目的重点是合成带有一个或两个可聚合官能团的功能化离子液体，它们的聚合，通过宽带介电谱研究离子液体和由它们制成的聚合物，以及研究这些聚合物作为气体分离和燃料电池膜的适用性。 合成了具有阳离子或阴离子链段的均聚物和具有阳离子和阴离子链段的共聚物以及交联的离子聚合物，并使用光谱和热分析方法对其进行了表征。 热聚合和UV-Vis诱导的聚合用于聚合物合成。 高分子链的动力学及其与气体分子的相互作用对于高分子作为气体分离膜的应用是非常重要的。 此外，对聚合物的流动性和导电性的研究集中在它们作为燃料电池膜的应用上。 所制备的聚合物的性质和通过宽带介电谱获得的结果是用于应用测试的聚合物选择的基础。 此外，在应用测试期间获得的结果是合成其它聚合物的共同基础。
