| Summary: | 碩士 === 國立成功大學 === 材料科學及工程學系碩博士班 === 101 === Titania nanofibers were successfully electrospun onto the titanium expanded meshes, which served as the replacement of ITO substrates. Randomly deposited titania nanofibers from the polymer-assisted electrospinning were conducted for the fabrication of the nano-scaled fiber scaffolds with light scattering behavior. The adhesion between titania nanofibers and the titanium meshes was carefully investigated via the prefabricated layer on titanium meshes and other approaches. Titanium meshes deposited with electrospun titania nanofibers were then electrodeposited with tungsten oxide as the conformal outer layers. Obtained TiO2/WO3 core-sheath nanofibers exhibited the high optical density as the electrochromic device. During the electrodeposition of WO3, it showed the deposition distribution as a function of distance to the conductive titanium meshes. For uniform and consistence WO3 outer layers, the electrodepositions were examined under the different applied voltages in both DC and AC voltages. Finally, three titanium meshes with different metal/hole ratios with WO3-coated titania nanofibers were investigated in their electrochromic performance.
