Fabrication of ordered TiO2 nanoribbon arrays by electrospinning

TiO2 has wide applications in chemical industry. In this manuscript we describe the ordered TiO2 nanoribbon arrays fabricated by electrospinning. A modified collector with a pair of split electrodes was employed to collect the TiO2 nanoribbon arrays during the electrospinning. The morphology and the structure of the resulting arrays were analyzed by scanning electron micrograph. It was found that the morphology of the aligned TiO2 ribbon arrays could be controlled by the spinneret geometry and the applied voltage. The ordered degree of the aligned TiO2 nanoribbon arrays could also be controlled by the environmental relative humidity. (C) 2009 Elsevier B.V. All rights reserved.
