Electrospun ZrO_2 fibers obtained from polyvinyl alcohol/zirconium n-propoxide composite fibers processed through halide free sol-gel route using acetic acid as a stabilizer

摘要

Electrospun ZrO_2 fibers have been prepared by heat treating the composite fibers of polyvinyl alcohol and zirconium n-propoxide precursors. Composite fibers prepared from acetic acid stabilized electrospun solution show non-beaded behaviour and possess diameter in the range of 130-440 ran. Fibers have been characterized by XRD, SEM and AFM measurements. Tetragonal to monoclinic phase transformation takes place during the heat treatment of composite fibers up to 1050 C without the morphology degradation.
