Embodiment 1
[0037] In order to fully disperse the graphene powder in the plating solution, and the particle size is not easy to vary too much, the graphene powder is sieved to ensure the uniformity of the particle size.
[0038] After sieving the graphene powder, a graphene powder with uniform sheet diameter is obtained; after that, it is activated by heating at 300°C for 1 hour, which can remove oily impurities and gases on the surface of the powder, and improve the wettability with the solution .
[0039]Take 20 grams of activated graphene powder and place it in a self-made hexagonal plastic bucket, add 3ml of glacial acetic acid to wet the graphene, continue to add 60 grams of powdered copper sulfate and 15 grams of zinc particles (if the surface of the zinc particles is oxidized, it must be cleaned before use) 5% sulfuric acid is heated for dissolving treatment), and finally add 30ml of water, rolling for 25 minutes (if the time is too long, the coating will thicken). The rotating sp...
Embodiment 2
[0049] Its total process route is as follows:
[0050] Graphene powder→cleaning and degumming with acetone (soaking for 2 hours)→degreasing with lye (30 minutes)→electroplating nickel-copper alloy→vacuum heat treatment (700°C for 30min, 750°C for 30min, 800°C for 60min) and molten aluminum casting, etc.
[0051] In order to fully disperse the graphene powder in the plating solution, and the particle size is not easy to vary too much, the graphene powder is sieved to ensure the uniformity of the particle size.
[0052] After sieving the graphene powder, the graphene powder with uniform sheet diameter was obtained; followed by acetone cleaning and degumming (soaking for 2 hours), lye degreasing (30 minutes), and then heating at 300 ° C for 1 hour Treatment can remove oily impurities and gases on the surface of the powder, and improve the wettability with the solution.
[0053] The following electroplating process ratio is adopted:
[0054] Metal nickel (as NiCl 2 form added) ...
