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

该项目的目的是制备介观结构的功能复合非织造材料，包括静电纺丝聚合物纤维和超分子纤维。这些复合非织造布将在过滤和催化方面进行研究。为此目的，功能性聚合物和定制的超分子结构单元必须针对其应用专门合成。复合非织造布的制备将遵循两个新的概念。这包括最近发现的接枝自组装纤维的静电纺丝纤维，以及复合材料制造的静电纺丝和自组装纤维与定义的纤维长度的湿法成网工艺的系统调查。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。固定化金属离子和金属纳米粒子的非织造布在有机催化领域也有广阔的应用前景。

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.
