Preparation and Characterization TiO2 Aerogel Fibers

摘要：

　　TiO2 aerogel fibers have been fabricated by electron span combined supercritical drying technique.Polyvinylpyrrolidone (PVP)/TiO2 composite fibers are prepared by electrospinning PVP and TiO2 precursor Ti(OC4H9)4.TiO2 aerogel fibers are obtained by supercritical drying PVP/TiO2 composite fibers using ethanol as media.Structural of the aerogel fibers was investigated by scanning electron microscopy (SEM),X-ray diffraction (XRD) and N2 adsorption at 77 K.The effect of mass ratio of PVP/TiO2 was investigated.SEM shows that pore structure of nanofibers was well developed,with the diameter of nanofibers about 2 μm.N2 adsorption/desorption data show that the highest surface area of aerogel fibers reached 241.6 m2/g with the average pore diameter about 10 nm.The aerogel fibers were anatase type TiO2.
