Meanwhile, alongside my job and other projects, I continue to test various methods of coating models. This time, I made homemade conductive varnish (simply added copper powder to the varnish) and tried to deposit copper onto it using electroplating. However, since all the chemicals I ordered are still in transit, I tried the simplest electrolyte (copper sulfate, water, and sulfuric acid). Because the varnish turned out not very conductive, and its resistance (multimeter probes placed on the painted surface 10mm apart from each other) is in the hundreds of megaohms instead of the required 1-5 kilohms, the surface reluctantly grew copper. Also, due to the overly simple electrolyte, the surface quality turned out to be terrible (in the photo, the copper has already been sanded and polished, but initially, it was very dull because the electrolyte lacks brighteners). Nevertheless, the experiment is still interesting; it's amusing to observe copper depositing on plastic.
