摘要：
We have prepared polypyrrole (PPy) / MoO3 nanohybrid thin films and evaluated their volatile organic compound (VOC) gas sensing properties. The (PPy)(x)MoO3 thin films have been prepared by intercalation reactions of highly oriented MoO3 thin films. Intercalation of hydrated sodium ions successfully proceeded without loosing the crystallographic orientation. The (PPy)(x)MoO3 thin films was obtained by replacing the hydrated sodium ions with PPy. The (PPy)(x)MoO3 thin films can detect formaldehyde gas by increasing in their electrical resistance, whereas they showed no response to toluene.
