The electrical, structural, and chemical properties of twisted yarns of metal-oxide nanofibers,
fabricated using a modified electrospinning technique, are investigated in this report. In
particular, synthesized zinc oxide and nickel oxide yarns having diameters in the range of 4–
40 μ m and lengths up to 10 cm were characterized, whose constituent nanofibers had
average diameters of 60–100 nm⁠. These yarns have one macroscopic dimension for
handling while retaining some of the properties of nanofibers.
