Embodiment 1
[0036] (1) Disperse 0.3g of sodium lauryl sulfate in 10mL of absolute ethanol, and ultrasonicate at room temperature with a power of 360W for 10min until the solution becomes clear, and obtain the soaking solution for modification;
[0037] (2) Put 0.3g of expanded graphite in the soaking solution for modification, let it stand in a vacuum environment for 10 minutes, then take it out, dry it at 80°C for 30 minutes, and cool to room temperature to obtain the modified expanded graphite matrix material;
[0038] (3) Ultrasonicate the excess liquid disodium hydrogen phosphate dodecahydrate until it is completely clarified in a water bath at 50°C, and slowly add it dropwise to the modified expanded graphite matrix material until it is completely submerged. In the ultrasonic cleaning machine, heat the water bath and perform ultrasonication while vacuuming, take it out after vacuum ultrasonication for 5 minutes, repeatedly use filter paper to remove excess liquid disodium hydrogen pho...
Embodiment 2
[0041](1) Disperse 0.1g of cetyltrimethylammonium chloride in 10mL of absolute ethanol, and ultrasonicate for 10min at room temperature with a power of 360W until the solution becomes clear to obtain the soaking solution for modification;
[0042] (2) Put 0.3g of expanded graphite in the soaking solution for modification, let it stand in a vacuum environment for 10 minutes, then take it out, dry it at 80°C for 30 minutes, and cool it to room temperature to obtain the modified expanded graphite matrix material;
[0043] (3) Ultrasonicate the excess liquid disodium hydrogen phosphate dodecahydrate in a 50°C water bath until it is completely clarified, and slowly add it dropwise to the modified expanded graphite matrix material until it is completely submerged. Under a 50°C water bath, place the vacuum device on In the ultrasonic cleaning machine, heat the water bath and perform ultrasonication while vacuuming, take it out after vacuum ultrasonication for 5 minutes, repeatedly use...
