Abstract
TiO2 and polystyrene sulfonic sodium (NaPSS) composite film humidity sensors were prepared through dip-coating method. The polystyrene sulfonic sodium (NaPSS) was dip-coated onto the surface of TiO2 porous film on alumina substrate to fabricate the humidity sensor. The electrical properties of the sensor were measured. The TiO2/NaPSS composite film exhibited better sensing properties than the pure polymer NaPSS humidity sensor, such as smaller hysteresis and quicker response-recovery time.
