We investigate the formaldehyde gas sensing properties of poly(5,6,7,8-tetrahydro-1-naphthylamine)-intercalated MoO3 thin films ((PTHNA)xMoO3). The resistance responses of (PTHNA)xMoO3 to formaldehyde increase with increasing intercalation temperature. X-ray photoelectron spectroscopy reveals that the molar ratio of Mo5+ decreases with increasing intercalation temperature.
