| Outline of Final Research Achievements |
We have proposed a new type of organic hydrogen gas sensor in which palladium-coated poly(vinylidene fluoride) (PVDF) films are utilized. The chemical reaction on the palladium surface of the sensor was investigated by using an infrared absorption spectroscopy in the multiple internal reflection geometry (MIR-IRAS). We suppose that Palladium acetate plays an important role in the mechanism of hydrogen adsorption and desorption on the palladium surface.
The PVDF films fabricated by our wet process can be applied to other types of sensors such as pressure sensors and sphygmometers. We succeeded in depositing a patterned β-phase PVDF film on a surface-treated titanium film. The change in the output voltage of the PVDF film depends on the stress applied to the PVDF film. We confirmed that the patterned β-phase PVDF film worked as a pressure sensor.
