example 1
[0021]In parts by weight, mix 30 parts of graphene, 100 parts of alcohols, and 30 parts of potassium permanganate solution with a mass fraction of 30% into a three-necked flask, and stir and mix for 30 minutes at a speed of 500 r / min. Finally, drop sulfuric acid with a mass fraction of 30 into the three-necked flask with a rubber dropper to adjust the pH to 4.8, then move the three-necked flask into an ultrasonic disperser, and conduct ultrasonic dispersion at a constant temperature for 4 hours at a temperature of 100°C and an ultrasonic frequency of 60 kHz. , to obtain a dispersion, and pour the dispersion into a ball mill tank, add zirconia ball mill beads according to the mass ratio of ball to material 20:1, and after ball milling and mixing for 60 minutes, filter to obtain a filter residue, and wash the filter residue 5 times with deionized water, Then transfer the washed filter residue to an oven, and dry it to a constant weight at a temperature of 110°C to obtain modified...
