摘要：
Advanced TiO2 micro- and nano-fibers are synthesized combining electrospinning and sol-gel techniques. Original co-solvent approach is applied for preparation of spinnable solutions based on polyethylene oxide (PEO) and titanium isopropoxide (TIP). Two-steps thermal processing is developed for calcination of the as-spun composite fibers. Influence of PEO/TIP weight ratio on the fiber morphology is demonstrated via scanning electron microscopy. Based on X-ray and transmission electron diffraction analysis, opportunity for preparation of TiO2 fibers consisting of anatase, brookite and oxygen deficient phases is demonstrated. The results obtained are encouraging for development of TiO2 functional materials for application in photocatalysis and biomedical engineering.
