How to electrodeposit copper nanoparticles

August 20, 2017

Q. If I synthesize leaf-mediated copper nanoparticles, it's also used in electroplating processes. The processes are running copper plating on steel, but the plating is not stable; after drying it's destroyed. What I will do sir?

Hi Mekala. Unfortunately it is not at all clear what you are trying to do or why. So when you ask why it's not working, I am lost.

Are you trying to deposit copper nanoparticles onto a surface with good adhesion? How are you going about it?

Are you trying to electrodeposit copper nanoparticles rather than dissolving the copper into ions in solution? To my knowledge, that won't work, although it might be possible to occlude those nanoparticles into conventional copper electroplating such that you have a composite copper surface with some of the properties of copper nanoparticles if the copper plating solution doesn't dissolve them (you might consider cyanide plating instead of acid plating).

What do you mean by "destroyed"? The coating falls off, the nano properties are lost, it doesn't look right, or what?
