Abstract

Two novel precursors, polyacetylacetonatotitanium (PAT) and polyacetictitanium (PET), which can be applied for the preparation of TiO2 fibers, were synthesized by metathetical polycondensations. The fibers of PAT and PET were prepared by sol–gel dry-spinning method. The high-quality and plentiful precursor fibers were easily collected with the diameter of 2–20 μm. The structures of the precursors were characterized and analyzed by elemental analyses, X-ray fluorescence spectrometry, infrared spectral analysis, nuclear magnetic resonance analysis, and thermal analyses. Both PAT and PET are the linear polymers containing Ti(OH)2Ti chains. The coordination number of titanium atom is 8. And each titanium atom is coordinated with six –OHs and one CH3–CO−=C–CO–CH3 (for PAT) or CH3–COO− (for PET). The precursor fibers can be used to prepare TiO2 fibers at 500 °C. The TiO2 fibers exhibit fine photocatalytic degradation activities.
