We have proposed a new type of organic hydrogen gas sensor in which palladium (Pd)-coated β-phase poly(vinylidene fluoride) (PVDF) films are utilized. Volume expansion of the Pd thin film caused by absorption of hydrogen gas is monitored by a piezoelectric film of PVDF attached to the Pd films. We have developed a simple method of synthesizing polar β-phase PVDF films from non-polar α-phase PVDF powder by using a wet process in which a mixture of acetone and hexamethylphosphoric triamide is used as the solvent for the PVDF powder. The sensor works by itself at room temperature without a power source. |
