Abstract

PURPOSE:To obtain a highs sensitivity polymer gas sensor, by applying heat- treatment to a composition, which is based on polyimide and to which a catalyst is added, in air. CONSTITUTION:1-10wt% of SnCl4 and 0.5-7wt% of a benzonitrile palladium complex are added to polyimide. The resulting composition is dissolved in a solvent consisting of 55% of N-methyl-Z-pyrrolidone, 35% of dimethylacetamide and 10% of toluene to be applied to a substrate and the coated substrate is treated at 300-500 deg.C, pref., at 450 deg.C for 20min in air while rotated. By this constitution, a gas sensor usable in a wide range containing considerably high temp. and having excellent gas sensitivity is obtained and useful for the detection of H2, other combustible gas or noxious gas.
