Abstract:

Flexible γ-Al2O3 nanofibrous membranes were prepared by sol-gel combined electrospinning technique using aluminum chloride and aluminum isopropoxide as raw materials, water and ethanol as the solvents. The morphology and mechanical property of the membranes were characterized and the formation process was tracked. The membranes were composed of uniform nanofibers with a mean diameter of ca.188 nm. The fibers’ surfaces were smooth and the fibers were composed of nanoparticles with a size range of 15—30 nm. The prepared membranes exhibited excellent flexibility and tensile strength(1.01 MPa).

Key words: Al2O3, Fibrous membrane, Mechanical property, Electrospinning
