Capacitive Humidity Sensors using lodine-doped Polyphenylacetylene Thin Films

  • 발행 : 2000.06.01

초록

We report the results of a preliminary investigation on capacitive humidity sensors using iodine-doped polyphenylacetylene(PPA) thin films. PPA was prepared from phenylacetylene(PA), chemically doped with iodine, and characterized by DSC, $^1H$-NMR and FTIR spectra. The iodine-doped PPA sensors showed a sensitivity of 0.20pF/%RH, a linearity of 3.8%FS, a negligible hysteresis, and a low temperature coefficients of $0.043~0.067pF/^{\circ}C$ over a wide range of relative humidity. These results are expected to open up the possibility of iodine-doped PPA thin films as relative humidity sensors.
