Mesoscopically structured functional composite nonwovens for application in separation and catalysis (B08)

该项目的目标是制备由电纺聚合物纤维和超分子纤维组成的介观结构功能复合非织造布。这些复合非织造布将在过滤和催化方面进行研究。为此，必须根据其应用专门合成功能聚合物和定制的超分子构建块。复合非织造布的制备将遵循两个新概念。这包括对最近发现的将自组装纤维嫁接到电纺纤维上的系统研究，以及通过湿法铺设电纺纤维和具有特定纤维长度的自组装纤维的复合材料制造。这些复合非织造布将用于空气过滤和金属离子的液体过滤。具有固定化金属离子和金属纳米颗粒的非织造布也将用于有机催化。

The aim of the project is the fabrication of mesoscopically structured functional composite nonwovens consisting of electrospun polymer fibers and supramolecular fibers. These composite nonwovens are to be investigated in filtration and catalysis. For this purpose, functional polymers and tailored supramolecular building blocks have to be synthesized specifically with respect to their application. Two new concepts will be followed for the preparation of the composite nonwovens. This includes the systematic investigation of the recently discovered grafting of self-assembled fibers on electrospun fibers, as well as composite fabrication by wet-laid processes of electrospun and self-assembled fibers with defined fiber lengths. These composite nonwovens will be used for air filtration and for liquid filtration of metal ions. The nonwovens with immobilized metal ions and metal nanoparticles will also be used in organic catalysis.
