Embodiment 1
[0035] Cut the PET film with a thickness of 0.1mm into a surface area of 0.49cm 2 3-4 mg of flake-shaped molybdenum trioxide is coated on it, the preferred size of molybdenum trioxide is 5-10 nm in thickness, 20-50 nm in width, and 3-5 μm in length, and the ratio of aniline to molybdenum trioxide is 1 :10, 1:3, 10:1 mixed, under the catalysis of ammonium persulfate in acidic solution, aniline is attached to the acidic active sites on the surface of molybdenum trioxide to polymerize to generate protonated polyaniline, and a flexible conductive film is obtained. The electron microscope images of the flexible conductive film are as follows: figure 2 Shown in Figures a, b, and c.
[0036] Gained flexible conductive film is tested the triethylamine concentration in the scope of 0ppm~100ppm at room temperature, and the minimum monitoring concentration of triethylamine is 0.5ppm and its response value is 1.2, and when 1ppm, response value is 2.8 (response value is flexible conduc...
Embodiment 2
[0038] Cut the PET film with a thickness of 0.1mm into a surface area of 0.49cm 2 0.5-1.5 mg of rod-shaped tungsten trioxide is coated on it. The preferred size of tungsten trioxide is 10-20 nm in diameter and 1.5-2 μm in length. Aniline and tungsten trioxide are mixed at a weight ratio of 1:2. Under the catalysis of ammonium persulfate, aniline adhered to the surface of tungsten trioxide and polymerized into protonated polyaniline to prepare a flexible conductive film.
[0039] Gained flexible conductive film is tested at room temperature to the response value of 100ppm triethylamine, ethylenediamine, ammonia, ethanol, acetone, test result is as follows Figure 4 .
Embodiment 3
[0041] Use a PET film with a thickness of 0.1mm and cut it into a surface area of 0.49cm 2 A square film of 0.5-1.5 mg, a hollow tubular tin oxide with a wall thickness of 1-10 nm and a length greater than 1 μm is coated on it, and pyrrole and tin oxide are mixed at a weight ratio of 1:2, and ammonium persulfate is mixed in an acidic solution. Under the catalysis, pyrrole is polymerized on the surface of hollow tubular tin oxide to form polypyrrole, and a flexible conductive film is prepared.
[0042] Gained flexible conductive film is tested ammonia gas concentration data at room temperature as Figure 5 , to monitor the change of ammonia concentration in the environment during the petrochemical production process by monitoring the change of the resistance of the flexible conductive film.
