“…[1] WO 3 also has a wide energy gap, 2.6-3.6 eV, very useful in the photoelectric component field. [2] Many methods have been used to produce WO 3 nanofiber or nanocomposite material, including thermal oxidization, [3] templates, [4] chemical vapor deposition, [5] atomic layer deposition, [6] sol-gel dipcoating, [7] water heating, [8] electrostatic spraying, [9] dielectric-electrical discharge machining, [10] and electrospinning. [11] Of these, the electrospinning technique, which uses an electric field to spin macromolecules from a solution into a fiber, is simple and easy.…”
