Embodiment 1
[0033] 1. Add 0.06g of graphene oxide (GO) into 15mL of deionized water, and use a cell pulverizer at 500W to sonicate for 30 minutes at room temperature to obtain a graphene oxide suspension;
[0034] 2. Add 2g of polyvinylidene fluoride (PVDF) into 15mL of 1,4-dioxane solution, stir and dissolve with a glass rod to obtain polyvinylidene fluoride colloid;
[0035] 3. Use a plastic dropper to absorb the GO suspension and slowly drop it into the PVDF colloid that is being magnetically stirred to obtain suspension A;
[0036] 4. Volatilize the mixed solvent at room temperature under magnetic stirring to obtain GO / PVDF powder composite material;
[0037] 5. Use a small amount of 1,4-dioxane to stir the powdery composite material into a slurry, add 50mL of 5mg / mL Vc aqueous solution, stir magnetically to disperse the slurry in the Vc solution, and perform soaking and reduction. The temperature is 90°C, and the soaking reduction time is 24 hours;
[0038] 6. After soaking and red...
