Neuartige Strategien zur Immobilisierung homogener Katalysatoren durch Elektrospinnen
Diese Arbeit verfolgt verschiedene Konzepte zur Immobilisierung homogener Katalysatoren in elektrogesponnenen Polymerfasern bzw. -röhren. Als Trägermaterialien dienten Oligostyrol im Verbund mit Polystyrolfasern, verzweigtes Polyglycerin inkorporiert in Poly-p-xylylen-Röhren sowie vernetzter Polyvin...

This work investigates different concepts for the immobilization of homogeneous catalysts in electrospun polymer fibers and tubes. Different carrier systems were used (oligostyrene in combination with polystyrene fibers, branched polyglycerine incorporated in poly-p-xylylene tubes, cross-linked polyvinylalcohol, functionalized poly-p-xylylene tubes). Leaching studies were performed using UV/Vis- and fluorescence spectroscopy. The activity and selectivity of the immobilized catalyst was shown to be comparable to the activity of the solubilised catalyst.
