Synthesis of LiCl Doped Hollow TiO₂ Nanofibers via Electrospinning and Their Humidity-Sensing Properties

Abstract:

LiCl doped titania (TiO₂) hollow nanofibers were prepared by using polylactide (PLA) nanofibers as templates. The morphology and crystal structure of the TiO₂ hollow nanofibers were characterized by scanning electron microscopy, transmission electron microscopy, and X-ray diffraction. The as-prepared LiCl doped TiO₂ hollow nanofibers exhibited a good humidity-sensing property. During the relative humidity (50%-95%) measurement, the response and recovery time is about 3 and 4 s, separately, with good linearity. The relationship between the humidity-sensing properties and the structure of the hollow nanofibers was also discussed. These distinguished and sensitive sensing performances make this material a good candidate in fabricating humidity sensors.
