We show how to make conductive silver ink. 1g of silver acetate is completely dissolved in 2.5mL of ammonium hydroxide (30%). 0.2mL of formic acid is added dropwise with stirring. Solution is then capped and allowed to stand for 12 hours. The solution is decanted and then pushed through a 0.2 micrometer pore syringe filter. Draw it onto a surface and let it dry. Then heat it to 90 celsius to sinter it into solid silver. Procedure taken from http://pubs.acs.org/doi/abs/10.1021/ja209267c
insanely cool. this is something i could really make use of. thank you very much for this, nurd!
thanks for sharing this. Would this be effective as a prep method for carbon foams prior to electroplating?
hello, thanks for video, a question: after sintered, the silver layer adheres well into substrate? glass for example?
I don't know about glass. But it does work well with ceramic and fibreglass.
Hi, very interesting the ink!! I read this paper a few months ago... I'll try to use in my inkjet to print complex circuits! I was thinking, if you use cupper acetate, will work too?
could you make this with copper? I need to do this for a layer on plastics so I can electroplate them after
whats the best concentration of the formic acid in this case?
Hello.Really awesome tutorial. Would it perhaps be possible to use heat transfer paper because that can handle the heat and also photo resistant paper or does it not work wit all types of paper
you could build a simple cnc machine with this ink and print on your board. Good concept.
NurdRage, in the supplementary information of that paper it says you can add 10% 2,3 butanediol (by volume) which serves as both a humectant and viscosifying aid. You should add it and try to apply the ink on paper again.
sir please I need to make a conductive Gold ink with the same way by heating
Can we do it with copper ?
Thank you very much for the videos.
copper acetate completely dissolve in ammonium hydroxide with formic acid
amazing. thanks.
Sir
I need to asking you if I put this ink on glass cup and heat to 600 C ? shall I have a bright layer or not?
would this also work with copper acetate?
Nurd, I've watched A LOT of your videos, and I'm still wondering this since the first video I've seen: is that your real voice?
Can this process be used to create silver tin-type photographs?
Thank you very mutch for this nice Video !!!
How long does it take to evaporate?
can you use a torch to heat up the silver ink at the end?
Does it work with aluminium, copper or gold?
Dammit Gary.
The thing looks like a silver-gecko :)
I noticed that the resistance (if that's what you're measuring) continues to go down as you're holding the probes to the ink. Is this a chemical process or just some quirk of the ohmeter?
Would it be possible to use that ink on glass surface to make a mirror?
it gives an easier way to do it
if you look for Diy mirror, you should find tutorials for it.
they are chemicals needed are less "dangerous" and easier to handle
you also can use a old printer (buy a cheap used one with no chip inside the inktanks Like epson stylus colour 300) and you can print the chemicals onto a glass
@Sebastian Schmidt
That "easier" way of making mirrors is very wasteful, you need to prepare lots of solution which all goes to drain after use. also none of those chemicals are dangerous besides silver salts that stain everything horribly.
using this ink for printing conductive tracks is not very suitable either, because conductivity is quite low it is only useful as initiator for galvanic copper or silver deposition
I am planning to use it for pcb vias or copper plating
I find it so crazy that something that looks exactly like water (albeit a lot more viscous) can dry into something so metallic. It's a mind-blower.
Could That be Used to make Metal plated Holes and Vias?
this lasts much longer and won't produce the dangerously explosive nitrides like the silver nitrate based versions. So go for it :)
I heard silveramine complexes are explosive. How could you say it will not produce nitrides? Could u kindly reply.
Why did formic acid instead add ammonia formate?
random question on an old video, but could you use this as (somewhat permanent) thermal paste?
@Cassidy Boon Meme's games are still made with dx11, so it was (until dx12 release) top of the line API
what about how most games don't even use direct x but OpenGL for its cross compatibility
@Cassidy Boon Meme's
nope. most games use dx because of the performance advantages, and usually have opengl as selectable, because reasons?
they perform the same???
@Cassidy Boon Meme's nope. Close, but no.
Hi, I am a new subscriber please make a video on silver nitrate permanent ink.
anytime I see a screen in your videos like @ 0:24 I instantly sigh, even if I never planned on trying an experiment myself.
Does this stuff respond to flexing or pressure? Could it be used to make sensors?
thank i love the nurd rage channel thanks alot
Its very hard to get formic acid where I live ;/. I may dry distill some ants lol
hello again, sorry using this post, but would you have some video how to make KAu(CN)2 ? it is much used in electroless plating.
I'm guessing your favorite element is silver, huh?
I need this, where can I buy some mLs? Or where can I get the somponents to make it?
Cool vid how thiin could you make the traces with something like that? the links at the end go to the save video though.
0:37 Stirring bar: They see me rollin' They heatin'
I'm late but I just wanted to say that this is cool
Do a video of how to make C20H25N3O
That looks like a lizard. :)
Where do you buy this stuff
if you get to dissolve in another medium (for example 15% KCN-solution ;-) ).
can you use silver nitrate from nitric acid? i.e silver refining? you could draw on copper with this too? dont know about the fuse bit at the end working though.
how to make syringe filter
Could you please upload something about white phosphorus, I've got some chunks about the size and shape of cigarettes imersed in water and I dont have the guts and knowlege yet to cut them...
wooooooooowww
is this what thermal compound is ?
Lol... Could you put this into a pen?

My expectations were thoroughly crushed. Well done.
