As precursors, graphite oxide samples are exfoliated and used to prepare graphene oxide thin films by gassp in coating with Ag-Pd integrated electronic device(Ag-Pd IED). The graphene oxide thin films are annealed at 80—180℃ to obtain a series of reduced graphene oxide gas sensing element samples with different reduction degrees,and the layer structures, film thickness and functional groups change properties of all the samples are investigatedby X-ray diffraction spectroscopy, Fourier transform infrared spectroscopy, Atomic force microscope and X-ray photoelectron spectroscopy. The prehumidification treatment with the relative humidity from 11.3% to 93.6%, thegas sensitivity tests are carried out to reduced graphene oxide thin film gas sensing element. Then the formaldehydegas sensing measurement are also implemented. The results show that the structure of the graphene oxide samplesare transformed to the graphitic structure after reduction at different thermal treatment temperatures. The oxygenfunctional groups on the surface of graphene oxide gradually pyrolyzed, the defects increase, the structure ofgraphene gradually changes to similar to graphite, and the resistance of the samples were significantly reduced inmagnitude with 41 MΩ to 928 Ω. The samples with different relative humidity pretreated produced competitiveadsorption of water molecules and formaldehyde molecules in formaldehyde atmosphere, leading to obvious changesin resistance. When exposed to the 10-4 formaldehyde gas at room temperature, unreduced or the reduced productsat low temperature show good sensitivity of 69.1% to formaldehyde gas in high humidity environment. In mediumhumidity environment, the reduced products at medium temperature which exhibit a best sensitivity of 80.3% are suitable for the test of formaldehyde gas.
