Paper Abstract

The copolymerized propylene-butyl of which the 'solubility parameter' almost coincides with that of hydrocarbon and organic solvent gases such as toluene, xylene, diethyether, chloroform and acetone, is chosen as a material of the sensing membrane coated on the quartz resonator. It is found that copolymerized propylene-butyl-film coated quartz resonator microbalance gas sensor exhibits high sensitivity and excellent selectivity for these gases, especially for toluene and xylene gas, suggesting that the 'solubility parameter' is effective to functional design of the sensing membrane of quartz resonator gas sensors.
