Embodiment 1
[0027] Embodiment one: the composition formula and preparation process of the present embodiment are as follows:
[0028] 1. Formulation
[0029] A. Composite membrane matrix material: DS is 68.02% SPEEK material, and the mass percentage is 90%.
[0030] B. Binary doped solid: nano-CeO 2 、H 3 PW 12 o 40 , the mass percentage is 10%, where CeO 2 and H 3 PW 12 o 40 The molar ratio is 1:1.
[0031] 2. Synthesis of SPEEK material with DS of 68.02%: Add 20g of PEEK powder and 800ml of concentrated sulfuric acid into a 1L three-necked flask, and stir the reaction at 60°C for 9 hours. After the reaction solution is cooled to room temperature, pass the reaction solution through the glass Pour the funnel into 4.5L of ice-water mixture, after cooling, rinse with a large amount of deionized water for 6 times, then let it stand overnight with 4.5L of deionized water, then rinse with deionized water for 3 times, and filter out the pink A colored SPEEK solid was obtained, and the ...
