Zirconium dioxide nanotubes from sol-gel coating of electrospun polymer fibers

Stable zirconia sol was prepared using inorganic salt (zirconia chloride octahydrate) as the precursor and H2O2 as the catalyst. ZrO2-PBS coaxial nanofibers were fabricated using the sol-gel coating technique to filling poly butylenes succinate (PBS) fibers with zirconium dioxide by electrospun. ZrO2 nanotubes were obtained via calcining ZrO2-PBS coaxial nanofibers. The ZrO2 nanotubes were characterized by TG, SEM and TEM, respectively. The results show that ZrO2 nanotubes with a diameter of 50 similar to 100 nm are obtained after calcining ZrO2-PBS coaxial nanofibers at 450 degrees C.
