Provided are a carbon dioxide sensor based on THEED fibre arrays and a preparation method therefor. In the preparation method, by spraying a polymer solution by an electrostatic spinning device in combination with feeding by a linear high-speed moving table (2), the spinning of density-controllable oriented THEED polymer micro/nano-fibre arrays is achieved; and thereafter, by modifying a resistance layer of a nickel-chromium alloy thin film through magnetron sputtering, the carbon dioxide sensor based on THEED fibre arrays is obtained. In the preparation method, only a small amount of polymer solution and target material are used, the material having a low cost; by adjusting the feeding speed of the linear high-speed moving table, the oriented micro/nano-fibre array density can be freely controlled; by adjusting the solvent parameters and operating parameters, the oriented micro/nano-fibre diameter can be more precisely controlled; and by adjusting the sputtering parameters, adjusting the thickness of the thin film resistance layer can be achieved. |
