Abstract
Poly (Vinyl Alcohol)(PVA)/In-Sn hydroxide (ITH) nanofibers were prepared via electrospinning, then followed by calcining at 400 , 475 , and 550 to obtain indium tin oxide (ITO) nanofibers. The influencing factors of solution properties, viscosity and electrical conductivity on the formation and morphology of electrospun fibers was investigated. The microstructure of PVA/ITH and ITO nanocomposites were characterized by scanning electron microscopy (SEM). And the crystalline structure of ITO nanocomposites was analyzed by X-ray diffractometry (XRD). The results showed that the average diameter and variation coefficient of obtained PVA/ITH nanofibers decreased after the adding of ITH. The ITO nanofibers became thinner and more uneven with the increasing of calcined temperature. XRD patterns proved that ITO nanoparticles existed after calcined and showed the structure was strongly depended on the calcined temperature. The bixbyite and the corundum type could be fabricated according the calcined temperature.
