Embodiment 1
[0029] (1) Prepare 100mL of electrophoresis solution: Put 50ml of methyl 2-methacrylate (47.2g) and 250ml of water into a three-necked flask, heat the water bath to 70°C, put in 0.17g of recrystallized potassium persulfate, and react for 4h. Then the water bath was cooled to 50°C, filtered with 300-mesh gauze to obtain the template suspension, and kept at 6°C for use. Measure 10 ml of the template suspension prepared above into a beaker, add 90 ml of absolute ethanol, and stir evenly to obtain an electrophoresis solution.
[0030] (2) The zinc flakes (Shenzhen Ketianhua Glass Instrument Co., Ltd., with a zinc content of 99.5%) are smoothed on different types of sandpaper, cleaned with water, and then placed in a 2:1 ethanol-acetone mixture. Ultrasound at 40KHz for 20min, then rinse with water and set aside.
[0031] (3) Put the zinc flakes processed in step (2) into the electrophoresis solution prepared in step (1), use the zinc flakes as the anode, and the stainless steel flakes ...
Embodiment 2
[0037] (1) Prepare 100mL of electrophoresis solution: put 150ml of ethyl acrylate (141g) and 250ml of water into a three-necked flask, heat the water bath to 70℃, put 4g of recrystallized sodium persulfate, react for 4h, then cool to 50 ℃, filter with 300 mesh gauze to obtain the template suspension, and refrigerate at 6 ℃ for later use. Measure 10 ml of the above-prepared template and suspend it in a beaker, add 90 ml of absolute ethanol, and stir evenly to obtain an electrophoresis solution.
[0038] (2) Polish the aluminum sheet (Shanghai Luyi Metal Material Co., Ltd., brushed aluminum sheet) on different types of sandpaper, clean it with water, and then place it in the ethanol-acetone mixture with a volume ratio of 2:1, and ultrasonicate at 40KHz for 20min , Then rinse with water and set aside.
[0039] (3) Put the aluminum sheet processed in step (2) into the electrophoresis solution prepared in step (1), use the aluminum sheet as the anode, and the stainless steel sheet (Wux...
Embodiment 3
[0045] (1) Prepare 100mL of electrophoresis solution: put 100ml of ethyl 2-methacrylate (91.2g) and 250ml of water into a three-necked flask, heat the water bath to 70℃, put in 8g of recrystallized ammonium persulfate, react for 4h, then Cool to 50°C in a water bath, filter with 300 mesh gauze to obtain the template suspension, and refrigerate at 6°C for later use. Measure 10 ml of the above-prepared template and suspend it in a beaker, add 90 ml of absolute ethanol, and stir evenly to obtain an electrophoresis solution.
[0046] (2) Polish the copper sheet (Shanghai Zicheng Copper Co., Ltd., QAL9-4 bronze plate) on different types of sandpaper, clean it with water, and then place it in the ethanol-acetone mixture with a volume ratio of 2:1. Ultrasound at 40KHz for 20min, then rinse with clean water and set aside.
[0047] (3) Put the copper sheet processed in step (2) into the electrophoresis solution prepared in step (1), use the copper sheet as the anode and the stainless steel...
