Embodiment 1
[0032] A preparation method of high stability electrochromic device based on PSS, (1) Add 0.8 g of PEDOT: PSS in a 50 ml beaker, add 50 ml of deionized water, ultrasonic 30min. Three filtrations were filtered three times, and the resulting saturated solution was stored in the centrifuge tube. Subsequently, the ITO surface was spinned at 1000 rpm to the PEDOT: PSS aqueous solution, and the time was 60s, then placed at 140 ° C for 10 min for 10 min, and was spin coated PEDOT: PSS film.
[0033] (2) 3m rubber of the square hole in the spin coated PEDOT: PSS film, the solid-state electrolyte of the pre-gel state is dripped into the 3m rubber box with the dropper, and blows the bubble with a dropper The film dripped over electrolyte was placed in a vacuum drying box for 20 hours at 70 ° C. After drying, the solid-state electrolyte is applied to a layer of gel state in its surface, and the protective film on the other side is torn, cover the polymerized PTBTPA film on the surface, cover...
Embodiment 2
[0035] A method of preparing a high stability electrochromic device based on PSS, step (1) is the same as in Example 1.
[0036] (2) 3m rubber with square holes in white ITO, the solid-state electrolyte of the pre-gel state is even dropped into 3m rubber frame, and the bubbles are blown with a dropper, will drop The film of the electrolyte was placed in a vacuum drying case for 20 hours at 70 ° C. After drying, the solid-state electrolyte is applied to a layer of gel state in its surface, and the protective film on the other side is torn, cover the polymerized PTBTPA film on the surface, cover it flat and remove the air bubbles with forceps. The resulting device is placed at room temperature for 5 hours to dry, and the surface of the device is wiped clean with cotton PE. By testing the optical contrast of 680 nm after the number of different cyclic circles, the stability of the device is obtained. figure 2 Indicated.
Embodiment 3
[0038]A method of preparing a high stability electrochromic device based on PSS, (1) add 0.05 gpedot: PSS conductive particles in a mortar, ground into a sheet, and then add 1 g of deionized water to continue grinding until the ink shape The ITO is uniformly tiled with a spoon, and the PEDOT: PSS ink is uniformly ground with a 30 μm coater, and then placed at 140 ° C for 10 minutes in an oven to give a spin coating PEDOT: PSS film.
[0039] (2) 3m rubber of the square hole in the spin coated PEDOT: PSS film, the solid-state electrolyte of the pre-gel state is dripped into the 3m rubber box with the dropper, and blows the bubble with a dropper The film dripped over electrolyte was placed in a vacuum drying box for 20 hours at 70 ° C. After drying, the solid-state electrolyte is applied to a layer of gel state in its surface, and the protective film on the other side is torn, cover the polymerized PTBTPA film on the surface, cover it flat and remove the air bubbles with forceps.
