We wanted to electrodeposit polyaniline by CV analysis.
However, I got an OVERLOAD at the beginning and the gold dropped off a bit.
Later, I ran the CV again and got the following blue graph.
After that, as the gold dropped, the solution turned green, as shown below, can we assume that the PANI was polymerized but not attached to the gold?
Also, as the Pt electrode kept depositing black material and later stabilized, it also drew a blue graph as shown below.
If you know the reason, please reply.
Yikes - you're getting a lot of side reactions, and neither of those voltammograms show deposition. Do you have any indication that the PANI is "seeding" onto gold? It usually does this efficiently onto carbon electrodes, but I've never heard of that working on gold. If you have any kind of carbon electrode, try your deposition experiment/parameters with that, and if it works then you'll know it's the gold-PANI association that's the problem.
