Embodiment 1
[0020] Embodiment one: the composition formula and preparation process of the present embodiment are as follows:
[0021] 1. Formulation
[0022] (1). Composite membrane matrix material: DS is 62.4% SPPS material, and the mass percentage is 80%.
[0023] (2). Ternary doped phase: Y 2 o 3 、H 3 PW 12 o 40 and polyphosphazene derivatives mass percentages were 2.0%, 3.0% and 15.0%.
[0024] 2. Synthesis of SPPS material with DS of 62.4%: 20 g of polyphenylene sulfide powder and 800 ml of concentrated sulfuric acid were added to a 1 L three-necked flask, mechanically stirred at 60 °C for 6 h, and the reaction solution was cooled to After room temperature, the reaction solution was passed through a glass funnel and poured into 4.5 L of ice-water mixture. After cooling, it was rinsed with a large amount of deionized water for 5 times, then allowed to stand overnight with 4.5 L of deionized water, and then rinsed with deionized water. After rinsing three times, the white SPPS s...

[0028] Embodiment two: the composition formula and the preparation process of the present embodiment are as follows:
[0029] 1. Formulation
[0030] (1). Composite membrane matrix material: DS is 68.2% SPPS material, and the mass percentage is 80%.
[0031] (2). Ternary doped phase: Y 2 o 3 、H 3 PW 12 o 40 and polyphosphazene derivatives mass percentages were 3.0%, 3.5% and 13.5%.
[0032] 2. Synthesis of SPPS material with DS of 68.2%: Add 20 g of polyphenylene sulfide powder and 800 ml of concentrated sulfuric acid into a 1 L three-necked flask, mechanically stir the reaction at 70 °C for 6 h, and wait for the reaction liquid to cool to After room temperature, the reaction solution was passed through a glass funnel and poured into 4.5 L of ice-water mixture. After cooling, it was rinsed with a large amount of deionized water for 5 times, then allowed to stand overnight with 4.5 L of deionized water, and then rinsed with deionized water. After rinsing three times, the...
