Process for the preparation of polymer fibers containing nanoparticles and / or microparticles and ceramic fibers obtainable therefrom, the polymer fiber itself and ceramised fibers obtainable therefrom and their use

摘要

Process for the preparation of nanoparticles and / or microparticles comprising polymer fiber, these nanoparticles and / or microparticles consisting of metal-containing material, having the step: Co-electrospinning a core fluid and a shell fluid comprising the nanoparticles and / or microparticles, wherein the core fluid comprises a polymer present in solvent and the sheath fluid is one with a suspension of the nanoparticles and / or microparticles in solvent, the proportion in the sheath fluid Polymer ≤ 1 wt .-% based on the total weight of the sheath fluid and the polymer in the core fluid is selected from polysiloxanes, polysilazanes, Polysilsesquioxanen or mixtures thereof.
