Preparation and characterization of TiO2 fiber with a facile polyorganotitanium precursor method

TiO2 precursor fibers were prepared with a new facile polyorganotitanium precursor by a dry-spinning method. The synthesis process, structure of the precursor, and its evolution from the precursor to polycrystalline TiO2 fibers were studied by 1H nuclear magnetic resonance (1H NMR), Fourier transformation infrared (FTIR), X-ray diffraction (XRD), and differential scanning calorimetry and thermal gravimetry analysis (DSC/TGA). The average diameter of the fibers is in the range of 10–20 μm from scanning electron microscopy (SEM) and the length can reach tens of centimeters. The BET surface area of the fibers calcined at 500 °C/2 h is around 160.3 m2/g and decreases with temperature increase.
