Embodiment 1
[0023] A method for making graphene skeleton moxa paste, comprising the following steps:
[0024] 1) Preparation of graphene skeleton
[0025] ① A single carbon fiber with a diameter of 5 μm is used to weave a 12-layer net using the fishing net stitch method, and the mesh gap is controlled to 0.2mm. When weaving, every 4 layers are used as a composite layer to obtain a three-layer composite carbon fiber mesh with two empty bags inside. ;
[0026] ②Place the woven carbon fiber mesh in an aerobic environment at 580°C for 3.5 hours to obtain a pre-oxidized carbon fiber mesh;
[0027] ③Slowly sink the pre-oxidized carbon fiber web obtained in step ② into concentrated sulfuric acid with a concentration of 98% to obtain the first mixed solution;
[0028] ④ Slowly add potassium permanganate powder 5.5 times the total mass of the original carbon fiber to the first mixed solution obtained in step ③, and slowly stir with a glass rod for 2.5 hours to obtain the second mixed solution; ...
Embodiment 2
[0039] The whole is consistent with Example 1, the difference is:
[0040] 1) Preparation of graphene skeleton
[0041] ①A single carbon fiber with a diameter of 5 μm is woven into a 9-layer net by fishing net stitching, and the mesh gap is controlled to 0.1mm. When weaving, every 3 layers are used as a composite layer to obtain a three-layer composite carbon fiber mesh with two empty bags inside. ;
[0042] ②Place the woven carbon fiber mesh in an aerobic environment at 550°C for 3 hours to obtain a pre-oxidized carbon fiber mesh;
[0043] ④ Slowly add potassium permanganate powder 5 times the total mass of the original carbon fiber to the first mixed solution obtained in step ③, and slowly stir with a glass rod for 2 hours to obtain the second mixed solution;
[0044] ⑥ Slowly add pure water dropwise into the second mixed solution, the adding speed is controlled so that the temperature of the liquid in the container is not higher than 40°C, and the total volume added is tw...
Embodiment 3
[0048] The whole is consistent with Example 1, the difference is:
[0049] 1) Preparation of graphene skeleton
[0050] ①A single carbon fiber with a diameter of 7 μm is woven into a 15-layer net by fishing net stitching, and the mesh gap is controlled to 0.3mm. When weaving, every 5 layers are used as a composite layer to obtain a three-layer composite carbon fiber mesh with two empty bags inside. ;
[0051] ②Place the woven carbon fiber mesh in an aerobic environment at 600°C for 3.5 hours to obtain a pre-oxidized carbon fiber mesh;
[0052]④ Slowly add potassium permanganate powder 6 times the total mass of the original carbon fiber to the first mixed solution obtained in step ③, and slowly stir with a glass rod for 3 hours to obtain the second mixed solution;
[0053] ⑥ Slowly add pure water dropwise into the second mixed solution, the adding speed is controlled so that the temperature of the liquid in the container is not higher than 40°C, and the total volume added is ...
