Embodiment 1
[0027] A kind of manufacture method of graphene intelligent health care underwear, concrete steps are as follows:
[0028] (1) Add graphite powder with a component ratio of 1:18 into concentrated sulfuric acid, the concentration of the concentrated sulfuric acid is more than 98%, to obtain a graphene concentrated sulfuric acid solution, stir the graphene concentrated sulfuric acid solution for 10min, and let it stand set for 40min;
[0029] (2) Add the graphene concentrated sulfuric acid solution into 100 parts of concentrated phosphoric acid, the concentration of the concentrated phosphoric acid is greater than 85%, then stir for 6 minutes, and let it stand for 40 minutes; then cool the obtained solution to 4°C, and then add 2.5 parts of potassium permanganate and 2.5 parts of potassium dichromate, stirred for 6 minutes, then allowed to stand for 4 hours;
[0030] (3) Heat the solution obtained in the above step (2) to 30°C, then add 45 parts of deionized water, then heat to...
