제목 Fabrication and Characterization of Core-Shell Structured TiO2 Nanofibers
초록 Epitaxially grown titanium dioxide (TiO2) nanofibers containing single crystalline TiO2 nanowires with anatase structure were successfully fabricated by electropinning poly(vinylpyrrolidone) solutions mixed with hydrothermally synthesized titanium dioxide nanowires and titanium (Ⅳ) isopropoxide Ti(OiPr)4 precursor. Utilizing SEM and TEM, morphological examination was conducted. Structure and orientation of the epitaxially grown TiO2 single crystalline nanofibers were also identified by the combined techniques of XRD and selected area ED. Improved optoelectronic properties of TiO2 nanofibers were also identified with UV-Vis spectroscopy experiments. This work was mainly supported by the Human Resource Traning Project for Regional Innovation and the Converging Research Center Program (2013K001428) of Korean government.
