I am not a chemist so much of hard work is wasted. I am thinking of trying to make a conductive paint to use on my sea shells ect. so I can electroform from a copper plating bath. Can't wait to get my cellulose acetate to dissolve with acetone, add the metallic copper to make conductive paint, and paint on my sea shell substrates. Thanks again, very much, for all your science....
I very much appreciate your videos. Although your British accent is wonderful, as a "yank," I do well just to discern the deep Texas drawl. Kind sir, would you please list the first two chemicals used in this presentation?
Thank you so very kindly for your reply. In the video, you initially spoke of two less common chemicals that (forgive my spelling) sounded like "Ethylene Diamene" and "Monoethylemene." Those two have tested hearing, repeatedly. We leave in a month to spend three weeks in England, Scotland and Wales, caravaning. My ability to understand proper English shall be honed.
Paul Haarup those two are amines that complex the copper - ammonia will do the same thing but it stinks to high heaven - it helps improve copper ion concentration
Is possible to use TEA or tri-sodium-citrate? I haven't mono e di-ethanolamine. For better rheology for piezo inkjet, I suggest to add a wetting agent like 1octyl2pyrrolidone, an organic high boiling to avoid too fast drying like 2pyrrolidone.
The end result color of the solution reminds me of the oxide of a home made photocell from superheated copper. Without sintering does this generate voltage from light in contact with graphene or a metal? Your previous video has me wondering if the light in the room is creating a self electroplating solution.
Robert Murray-Smith After seeing the results of your experiments I think it might generate voltage. Don't know for sure. Our perception of color could be altered by concentration and background.
I can't help but to think of you as the *Graham Kerr of Chemistry*.
Eagerly awaiting an electroluminescent ink jet version! :)
lol - thanks - i think! - i'll get EL soon enough lol - actually more like when i can lol

Hello, I really love your work and the way you explain things. Just amazing. I just wanted to know if this ink will print on plastic surface. TIA
Fantastic!
cheers mate
Hello sir, do you have any tutorials for injection conductive copper ink in to cartridges?
♡
If mix ascorbic acid and copper sulfate will be a green solution, but you have a different color. Why? Thank you.
different temp and different concentrations - review the video using glycol
Hello! Is this the same compound used in other vidoes for the rub on copper plating?

Robert Murray-Smith Thank you for your time, sir.
pahaarup no worries

It's well worth trying TEA or ammonia i might even try EDTA. thanks for the ink advice
Hey Robert, I sent you an email asking a couple of questions. I love your videos !
Paloma Carvalho i will have a look and i am glad you like the vids

do you know mate - i don't know but that is a very good question - if it was the same as a copper oxide photocell it would be brick red by the way

Michael Meadows
definitely worth a look at mate
Dear Robert Murray-Smith.
What materials do you apply for make Copper Nanoparticles Suitable For Ink Jet Printing? Thank you.
I did a video on it mate
What size would these nanoparticles be, approximately?
Also, how would one go about making this with ammonia instead?
Why does CuO nanoparticle ink require higher energy to be sintered when compared to Ag nanoparticle ink?
+Arvind G you have to reduce it to copper
Thanks a lot. :)
