Embodiment 1

[0061] First, configure the ion source solution, weigh lithium perchlorate and propylene carbonate at a mass ratio of 1:2, mix and stir thoroughly for 4-6 hours to form a clear and transparent solution, and store it away from light. Then weigh propylene glycol methyl ether acetate, photocurable resin UC-35 (Zhejiang Namei New Materials), stabilizer ferrocene, BYK1130, ETPTA and lithium ion according to the mass ratio of 2:1:1:0.1:1:1. solution, and stirred thoroughly for 30 minutes and then stored away from light. The configured solution is the resin slurry capable of conducting cations;

[0062] The obtained resin slurry capable of conducting cations was coated on the surface of the substrate, and uniformly irradiated with a 100W ultraviolet lamp for 15 minutes to obtain the resin film. The resulting resin film had a thickness of 80 µm. By judging the performance of electrochromism, embodiment 1 is the best performance.

Embodiment 2

[0064] First, configure the ion source solution, weigh lithium perchlorate and propylene carbonate at a mass ratio of 1:2, mix and stir thoroughly for 4-6 hours to form a clear and transparent solution, and store it away from light. Then weigh propylene glycol methyl ether acetate, polyethylene oxide with a molecular weight of 500,000, ferrocene, BYK1130, ETPTA and lithium ion solution according to the mass ratio of 2:1:1:0.1:1:1, and fully stir for 30 minutes to avoid light save. The prepared solution is the resin slurry capable of conducting cations.

Embodiment 3

[0066] First, configure the ion source solution, weigh sodium perchlorate and propylene carbonate at a mass ratio of 1:2, mix and stir thoroughly for 4-6 hours to form a clear and transparent solution, and store it away from light. Then weigh propylene glycol methyl ether acetate, photocurable resin UC-35, ferrocene, BYK1130, ETPTA and sodium ion solution according to the mass ratio of 2:1:1:0.1:1:1, and fully stir for 30 minutes before avoiding light save. The configured solution is the resin slurry capable of conducting cations;

[0067] The obtained resin slurry capable of conducting cations was coated on the surface of the substrate, and uniformly irradiated with a 100W ultraviolet lamp for 15 minutes to obtain the resin film. The resulting resin film had a thickness of 80 µm.

Abstract

The invention relates to cation-conducting resin slurry, a preparation method and application thereof. The cation-conducting resin slurry is prepared from a solvent, a resin, a stabilizer, an ultraviolet absorbent, an organic precursor and an ion source solution, wherein the organic precursor includes an acid ester compound, preferably one of ethoxylated trimethylolpropane triacrylate ETPTA and trimethylolpropane triacrylate TMPTA, the resin comprises a light-cured resin or/and a heat-cured resin, and the mass ratio of the solvent to the resin to the stabilizer to the ultraviolet absorbent to the organic precursor to the ion source solution is (1-5):(0.5-5):(0.1-2):(0.01-0.2):(0.5-5):1.

Description

technical field [0001] The invention relates to a cationic conductive resin slurry and its preparation method and application, and belongs to the technical field of chemical material synthesis and functional materials. Background technique [0002] Under the background of energy saving and emission reduction, electrochromic devices are mainly composed of five layers of thin films, including two transparent conductive layers, an ion storage layer, an electrochromic layer, and an ion conducting layer. Wherein, the ion storage layer assists the electrochromic layer to apply a low voltage on the first and second conductive layers to realize the electrochromic reaction. The ion-conducting layer provides lithium ions and a diffusion film layer, and is responsible for ensuring ion conductivity under the action of an electric field. Its structure and preparation process are one of the most important technologies to ensure the electrochromic performance of the device. Electrochromic...
