title: Preparation, Characterization and Sensitive Gas Sensing of Conductive Core-sheath TiO(2)-PEDOT Nanocables.
abstract: Conductive core-sheath TiO(2)-PEDOT nanocables were prepared using electrospun TiO(2) nanofibers as template, followed by vapor phase polymerization of EDOT. Various techniques were employed to characterize the sample. The results reveal that the TiO(2) core has an average diameter of ∼78 nm while the PEDOT sheath has a uniform thickness of ∼6 nm. The as-prepared TiO(2)-PEDOT nanocables display a fast and reversible response to gaseous NO(2) and NH(3) with a limit of detection as low as 7 ppb and 675 ppb (S/N=3), respectively. This study provides a route for the synthesis of conductive nanostructures which show excellent performance for sensing applications.
