Abstract: The present disclosure relates to a novel composite film configured for CO2 sensing, and the method of making and using the novel composite film. The novel composite film comprises a carbon nanotube film and a CO2 absorbing layer deposited on the carbon nanotube film, wherein the CO2 absorbing layer comprises a mixture of a branched polyethylenimine, a polyethylene glycol, and poly[1-(4-vinylbenzyl)-3-methylimidazolium tetrafluoroborate] of formula I:






wherein n ranges from 10-300.
