Conductive Silver Ink from a Ballpoint Pen

Materials researchers at the University of Illinois, Urbana-Champaign have developed a highly conductive silver ink. In this video, Analisa Russo, a graduate student in the research group of Professor Jennifer Lewis shows exactly how to make this amazing ink, which could be used for a wide variety of hobby projects and in advanced electronics hardware.

Amazing! Thanks for sharing the recipe! If only I had access to a lab....

[@Passi87]

Doing this right now, color is slowly changing! Fingers crossed xxx

[@akshitasharma5340]

Awesome!

[@bruceliu1657]

I would try this with a fountain pen.

[@bowu2094]

Hi, So what is the molecular weight you were using for the HEC?

[@crmusicproduction]

can this ink be used for metal plating? i.e gold, silver etc?

[@bagofchips8813]

will this work on my honda?

[@pauloesperon7697]

could someone estimate the cost of supplies? I dont mean to be lazy I just have no clue where to get the chemicals. Exclude the hardware

[@Jokreher]

That’s cool.

[@bowu2094]

my particle always separated into two layers, the sediment looks pale white, and the supernatant looks wine red.

[@friebender]

Are there specific Books about the manifacturing of silver ink? I didn't found much, or better said almost nothing except some low info pdfs.

[@rahul252592]

I need this pen, where can i get this pen. Is their any online purchase?

[@brianelliott5192]

Does the ink still stain peoples skin like silver nitrate?

[@permababy]

I think this is fantastic but has anybody looked up the price of silver nitrate?

[@OnBatteries]

Is anything using this recipe or of this quality available anywhere? I'm not able to make it on my own, unfortunately.

[@rEsonansDx]

Is its conductivity same with natural silver?

[@germanmendez8470]

I could sell one and how much slope

[@ASISTRADE]

That at the end sprayed in the pen?

[@jamalmohammad8374]

Its just canned air, to force the ink down in order for it to reach the ball (tip) of the pen

[@johnhopkins6260]

specs specs specs... ampacity and/or equivalent wire gauge - mm2

[@Roman1Diz]

Где купить такую?

[@Rich77UK]

Great. But it's hardly diy :(

[@Benloadeon]

conductive ink + phone blocks *O*

[@lynxlive555]

conductive ink = lead based paint..

[@hypnotiiqe]

Fire hazard :/

[@ntme9]

Well if this doesn't work out she will always have a phone sex hotline job waiting for her. I wonder what the conductivity specs of a single line are, amp rating*?

[@ntme9]

20ohms* nice
