Abstract

The work is focused on novel meso-structured bicomponent porous nanofiber mats made by electrospinning with special fiber morphologies, such as side-by-side (Janus), off-centered fiber and layer-by-layer structures, arrangement of two different polymers. The mutual interaction between the two components, both capable of having their own supramolecular structures, could lead to novel meso-structured porous materials with special properties. Bombyx mori silk and synthetic polymers (semi crystalline poly(L-latide), polycaprolactone, thermoplastic polyurethane and thermoresponsive poly(N-isopropylacrylamide), showing a LCST-type phase transition) were used for making bicomponent fibrous membrane and studies the synergetic effect.

Abstract in another language

Die Arbeit fokussiert auf neuartige meso-strukturierte Bikomponenten-poröse Nanofaser-Matten, die durch Elektrospinnen mit speziellen Fasermorphologien der Anordnung von zwei verschiedenen Polymeren: wie z. B. nebeneinanderliegende (Janus), abzentrierte Faserstruktur und Schicht-für-Schicht, hergestellt werden. Die gegenseitige Wechselwirkung zwischen den beiden Komponenten, die beide ihre eigenen supermolekularen Strukturen haben können, könnte zu neuartigen meso-strukturierten porösen Materialien mit besonderen Eigenschaften führen. Bombyx mori Seide und synthetische Polymere (halbkristallines Poly (L-latid), Polycaprolacton, thermoplastisches Polyurethan und thermoresponsives Poly (N- isopropylacrylamid), eine LCST-Phasenübergang gezeigt wird) wurden zur Herstellung von Bikomponenten-Fasermembran und Untersuchung der synergetischen Wirkung verwendet.
