Abstract

Alumina ribbons were fabricated facilely via using mixed solvent of ethanol and ethyl ether in electrospinning, and α-alumina ribbons were obtained after the as prepared ribbons were calcinated at 1200 oC for 1 h. The as prepared ribbons are composed of dense skin and porous inner structure, the thickness and width of which are of 1 μm and 3-5 μm respectively. After calcination, the corresponding sizes of the ribbons shrunk to ~ 200 nm and 2-3 μm separately. If solo solvent (ethanol) was used in the electrospinning experiment, only round alumina fibers were obtained..
