The invention provides the preparation and application of a sensing film for an ammonia gas sensor, and belongs to the technical field of gas sensors. The sensing film material is a polyaniline/reduced graphene oxide composite material; the polyaniline is a nano-spike-like structure, and the polyaniline is grown on the surface of the reduced graphene oxide layered structure. The ammonia gas sensing film based on the polyaniline/reduced graphene oxide composite material prepared by the invention has high sensitivity, high selectivity, strong repeatability and good stability, and the room temperature sensing greatly reduces the power consumption during the use of the sensor , which improves the portability of the sensor, and has important practical and research value in this technical field. |
