Embodiment 1
[0034] A method for efficiently preparing graphene is realized through the following steps:
[0035] (1) Weigh 4g of expanded graphite and 40g of potassium nitrate, the mass ratio of potassium nitrate to expanded graphite is 10:1;
[0036] (2) Add potassium nitrate and expanded graphite into a beaker with 80 mL of distilled water, heat and mix evenly until the potassium nitrate is completely dissolved, then place the beaker in a drying oven until all the water evaporates to obtain a mixture of expanded graphite and potassium nitrate, and then Put the mixture of expanded graphite and potassium nitrate into a ball mill jar with a volume of 1000mL, and add zirconium balls according to the ball-to-material mass ratio of 25:1;
[0037] (3) Then install the ball milling jar on the stirring ball mill, mill at a speed of 70 rpm for 2 hours, and pour out the ball milling product and zirconium balls from the ball milling jar;
[0038] (4) Rinse the ball milled product and zirconium bal...
