초록

In this study, titanium oxide($TiO_2$)/polyvinyl alcohol(PVA) electrospun composite nanofibers were used as a humidity sensing layer. The electrospinning behavior was observed to investigate the influence of different concentrations of $TiO_2$. In order to secure the structural stability of the sensing layer, which was dissolved under conditions of high humidity, the PVA-based sensing layer was crystallized at $180^{\circ}C$. The humidity sensing properties, including the impedance versus relative humidity and response-recovery time, were found to improve because of the structural advantage of the fiber-shaped sensing layer and the hydrophillic inorganic particles. Furthermore, The humidity sensing mechanism could be elucidated via the complex impedance plots and corresponding equivalent circuit.
