Embodiment 1
[0024] (1) Disperse silica nanofibers with an average diameter of 10nm and a length of 500nm and titania nanofibers with an average diameter of 10nm and a length of 500nm in ethanol. The masses of silica nanofibers and titania nanofibers are compared with ethanol. The mass ratio is the same as 7:3, and the slurry is obtained by ultrasonic for 20 minutes.
[0025] (2) Two carbon electrodes are coated on the base polyester resin film, the electrode width is 1 cm, the electrode length is 20 cm, and the distance between the upper electrode and the lower electrode is 4 cm.
[0026] (3) On the side of the substrate with the upper electrode and the lower electrode, the upper and lower ends are respectively coated with silica nanofiber slurry and titanium dioxide nanofiber slurry. After drying, an asymmetric moisture power generation device is obtained. The thickness of the coating It is 50μm.
[0027] (4) The device is placed in a humid environment with a humidity greater than 70%, and the...
