High Performance Humidity Sensor Based on Electrospun Zr_(0.9)Mg_(0.1)O_(2−δ) Nanofibers

         

摘要

Zr_(0.9)Mg_(0.1)O_(2−δ) nanofibers and ZrO_(2) nanofibers are synthesized using electrospinning and the calcination technique.The nanofibers are characterized using x-ray diffraction(XRD),a field emission scanning electron microscope(FE-SEM),and a Brunauer–Emmett–Teller(BET)surface analyzer.The humidity sensing properties of Zr_(0.9)Mg_(0.1)O_(2−δ) nanofiber sensors are analyzed and compared with those of ZrO_(2) nanofiber sensors.The Zr_(0.9)Mg_(0.1)O_(2−δ) nanofiber humidity sensors exhibit a broader humidity range of 11–97%relative humidity(RH),good linearity,small humidity hysteresis,and rapid response and recovery times.The complex impedance plots of the Zr_(0.9)Mg_(0.1)O_(2−δ) sensor at different RHs are drawn,and the humidity sensing mechanism is discussed via an equivalent circuit.
