Property analysis and humidity sensitivity of the composite material of BaTiO3 and RMX

Nanocrystal BaTiO3 and polymer (R)nM+X− are mixed to make a composite material. IR and XPS spectra of the composite material were analyzed and compared with those of BaTiO3. The humidity sensor made of the composite material shows better humidity sensing properties than the BaTiO3 sensor such as higher sensitivity and smaller humidity hysteresis.
