Abstract in another language

Functional polymer nanofibers were prepared by electrospinning of ternary polymer solutions (e. g. poly-L-lactide (PLA)) and low molecular weight metal compounds. These functionalized fibers were further modified by coating with poly(p-xylylene) (PPX) via chemical vapor deposition (CVD). Removal of PLA by decomposition or selective solvent extraction resulted in the formation of nanotubes with e. g. Pd-nanoparticles on the inside or outside of the tubes depending on the reaction conditions. Functional nanotubes available for numerous chemical modifications were obtained by the TUFT-process (Tubes by Fiber Templates). According to this process by PLA template fibers were coated with a mixture of poly(vinylalcohol) (PVA) and poly(acrylic acid) (PAA) followed by CVD of PPX as a protective coating. Heating of these composite fibers resulted in decomposition of PLA and chemical crosslinking PVA/PAA. Residual OH-groups were used as reactive sites for immobilization of functional small molecules such as anthracene derivatives. Co-electrospinning by coaxial jets of different materials resulted in fibers with concentric variation of materials concentration. For example, fibers with PLA shell and Pd core where obtained after co-electrospinning of PLA-chloroform and palladium diacetate - THF solutions followed by heating to 170 degrees C.
