Chemiresistive CO₂ sensors are promising for low-cost and miniaturized devices, but their sensitivity and selectivity remain challenging. Our group has achieved highly sensitive CO₂ sensing using polymer-coated SWCNTs; however, their selectivity is still inferior to that of existing systems. In this study, ZIF-78, which exhibits high CO₂/N₂ selectivity, was incorporated into polymer-coated SWCNTs and evaluated for CO₂ sensing. The relationship between adsorption properties and sensing properties was investigated through structural characterization, gas adsorption measurements, and sensing tests.
