Embodiment 1
[0030] This embodiment discloses a method for preparing graphite with metal-intercalated copper flakes, comprising the following steps:
[0031] Step 1: Preparation of layered flake graphite
[0032] (1) At room temperature, put 5ml of perchloric acid and 1ml of phosphoric acid into a glass beaker and mix evenly to obtain a mixed acid, then add 0.4g of potassium permanganate, stir slowly to dissolve it in the mixed acid, and finally add 4g Flake graphite and stir well to combine. Place the glass beaker filled with perchloric acid, phosphoric acid, potassium permanganate and graphite flakes in a constant temperature water bath with a water temperature of 40°C for 60 minutes. Stir continuously during the reaction to ensure uniform reaction. After the reaction was finished, it was washed with water several times, and the precipitated flake graphite was filtered out and dried at 60°C. Finally, put the obtained flake graphite into the muffle furnace, raise the muffle furnace to 3...
Embodiment 2
[0041] This embodiment discloses a method for preparing graphite with metal-intercalated copper flakes, comprising the following steps:
[0042] Step 1: Preparation of layered flake graphite
[0043](1) At room temperature, put 3ml of perchloric acid and 1.5ml of phosphoric acid into a glass beaker and mix evenly to obtain a mixed acid, then add 0.5g of potassium permanganate, stir slowly to dissolve it in the mixed acid, and finally add 3g flake graphite and stir well to make it evenly mixed. Place the glass beaker containing perchloric acid, phosphoric acid, potassium permanganate and flake graphite in a constant temperature water bath with a water temperature of 40°C to react for 60 minutes. Stir continuously during the reaction to ensure uniform reaction. After the reaction was finished, it was washed with water several times, and the precipitated flake graphite was filtered out and dried at 60°C. Finally, put the obtained flake graphite into the muffle furnace, raise th...
Embodiment 3
[0051] This embodiment discloses a method for preparing graphite with metal nickel flakes, comprising the following steps:
[0052] Step 1: Preparation of layered flake graphite
[0053] (1) At room temperature, put 5ml of perchloric acid and 1ml of phosphoric acid into a glass beaker and mix evenly to obtain a mixed acid, then add 0.4g of potassium permanganate, stir slowly to dissolve it in the mixed acid, and finally add 4g Flake graphite and stir well to combine. Place the glass beaker containing perchloric acid, phosphoric acid, potassium permanganate and flake graphite in a constant temperature water bath with a water temperature of 40°C to react for 60 minutes. Stir continuously during the reaction to ensure uniform reaction. After the reaction was finished, it was washed with water several times, and the precipitated flake graphite was filtered out and dried at 60°C. Finally, put the obtained flake graphite into the muffle furnace, raise the muffle furnace to 300° C....
