Embodiment 1
[0018] Embodiment 1 A kind of preparation method of copper surface gold graphene composite coating refers to:
[0019] Dissolve 0.4 g of gold chloride, 2.5 g of ammonium chloride, and 2 g of sodium sulfite in 50 mL of deionized water. Under stirring condition, 50mL concentration is the graphene oxide dispersion liquid of 4g / L and slowly adds in the above-mentioned solution, obtains component content and is: gold chloride 4g / L, ammonium chloride 25g / L, sodium sulfite 20g / L and Composite plating solution of graphene oxide 2g / L. Under stirring conditions, the pH value of the composite plating solution was adjusted to 13.0 with 40 g / L sodium hydroxide solution.
[0020] Then wrap the aluminum wire around one end of the cleaned pure copper sheet, and then directly immerse it in the composite plating solution at 30°C for 45 minutes. After plating, the sample was thoroughly cleaned with deionized water and dried with cold air to obtain a gold-graphene composite coating on the coppe...
Embodiment 2
[0022] Embodiment 2 A kind of preparation method of copper surface gold graphene composite coating refers to:
[0023] Dissolve 0.8 g of gold chloride, 0.8 g of sodium gold sulfite, 14 g of ammonium chloride, and 10 g of sodium sulfite in 100 mL of deionized water. Under stirring conditions, 100 mL of graphene oxide dispersion with a concentration of 6 g / L was slowly added to the above solution to obtain a component content of: gold chloride 4 g / L, gold sodium sulfite 4 g / L, ammonium chloride 70 g / L, a composite plating solution of sodium sulfite 50g / L and graphene oxide 3g / L. Under the condition of stirring, the pH value of the composite plating solution was adjusted to 13.5 by using 30g / L sodium hydroxide solution.
[0024] Then wrap the aluminum wire around one end of the cleaned copper sheet, and then directly immerse it in the composite plating solution at 30°C for 25 minutes. After plating, the sample was thoroughly cleaned with deionized water and dried with cold air...

[0026] Embodiment 3 A kind of preparation method of copper surface gold graphene composite coating refers to:
[0027] Dissolve 4 g of sodium gold sulfite, 6 g of potassium gold citrate, 75 g of ammonium chloride, and 60 g of sodium sulfite in 500 mL of deionized water. Under stirring conditions, 500 mL of graphene oxide dispersion with a concentration of 8 g / L was slowly added to the above solution to obtain a component content of: sodium gold sulfite 4 g / L, potassium gold citrate 6 g / L, ammonium chloride 75g / L, sodium sulfite 60g / L and graphene oxide 4g / L composite plating solution. Under the condition of stirring, the pH value of the composite plating solution was adjusted to 14.0 by using 40g / L sodium hydroxide solution.
[0028] Then wrap the aluminum wire around one end of the cleaned pure copper sheet, and then directly immerse it in the composite plating solution at 20°C for 12 minutes. After plating, the sample was thoroughly cleaned with deionized water and dried w...
