A new kind of polystyrene and surfactant, didodecyldimethylammonium, co-intercalated MoO<sub>3</sub> nano hybrids was prepared by chemical vapor deposition combined with wet process of simple immersion in an organic solution. The hybrid thin films have a characteristic structure of polystyrene and surfactant co-intercalation into MoO<sub>3</sub> with <i>b</i>-axis orientation on the LaAlO<sub>3</sub> (100) single crystal substrate. The hybrid thin films show a distinct response to acetaldehyde vapor by decreasing the electrical resistance. We discuss the possible sensing mechanism for acetaldehyde gas.
