Humidity sensors based on composite material of nano-BaTiO 3 and polymer RMX

The composite material made of nanocrystal BaTiO 3 and polymer material quaternary acrylic resin (RMX) can be used to make humidity sensors. The infrared (IR) and X-ray photoelectron spectroscope (XPS) spectra of the material were analyzed and compared with those of nanocrystal BaTiO 3. An equivalen...

Summary:The composite material made of nanocrystal BaTiO 3 and polymer material quaternary acrylic resin (RMX) can be used to make humidity sensors. The infrared (IR) and X-ray photoelectron spectroscope (XPS) spectra of the material were analyzed and compared with those of nanocrystal BaTiO 3. An equivalent circuit was given by analyzing the complex impedance plots of the composite material sensor. The electrical properties of the sensor were investigated, including resistance versus relative humidity, humidity hysteresis, response–recover time and long-term stability. The results indicated that the humidity sensing properties of the composite material is better than those of nanocrystal BaTiO 3.
