Solution spinning process for highly porous, nanostructured cellulose fibers

Kurzfassung

The conventional production methods for fibers from cellulose has up to now generated materials with a compact microstructure and a great aspect ratio. The open porous fibers presented here are a new kind of fibrous material and offer many challenges and opportunities for scientists and engineers. Due to the properties of nanostructured fibers they have a high potential for applications ranging from industrial scale products, e.g. from filtration to specialties, like drug-release scaffolds. By using a sol-gel routine it was possible to produce for the first time open porous, nanostructured cellulose fibers.
