The CO2 sensitive dielectric nanocomposite includes a low molecular weight organic containing a CO2 sensitive functional group, a resin, and P-type carbon nanotubes (CNTs). The method for fabrication of the capacitive CO2 sensor includes forming a CO2 sensitive dielectric nanocomposite including dissolving a low molecular weight organic containing a CO2 sensitive functional group in an organic solvent to form a first solution, dispersing P-type carbon nanotubes in an organic solvent to form a second solution, mixing the first solution and the second solution to form a nanocomposite solution, and adding a resin to the nanocomposite solution. The method further includes depositing the nanocomposite solution with the resin to form a solid nanocomposite film on a surface of a substrate with capacitive electrodes, and curing the nanocomposite film on the electrodes to form the capacitive CO2 sensor.
