keep submerged in salt water. What is cotton-ness?

>>1396950
softness

>>1396950
I need something permanent, or at least close to permanent. When the water evaporates it ceases to be conductive, iirc.

>>1396904
use steel wool instead?

>>1397001
No, it must be normal wool

>>1396904
Try to deposit silver on it a la silver mirror demonstration? Might be able to do the same thing with copper or another conductor, but silver should work. The mechanical route would be getting very fine copper wire and felting it into the cotton, though it may become somewhat abrasive. Both cases will likely not feel terribly soft, or at least have poor conductivity if they do, so perhaps looking into conductive plastics/rubbers is a better way to go.

Obligatory "what do you need it for". If it's a faraday business suit I'd be down for that.

>electrically conductive cotton without losing cotton-ness

Fill up a bong with mercury and stuff the cotton in the neck. Toke the shit out of it the fumes will impregnate the cotton making it conductive.

why you retard?

>>1396904
a match.

Treat with a mixture of sulfuric and nitric acid, neutralize with a base then water then let dry. Apply potential. Profit

>>1397159
Sounds like a real blast!

>>1397159
Sulfuric too? Don't you just need nitric if you want to make nitrocellulose, or is there something I'm missing?

>>1397120
I mean, it must be normal wool, plus some shit to make it conductive

>>1397345
>plus some shit to make it conductive
Like salt water? If you leave it in salt water permanently, the salt water idea is permanent.

>>1397190
You want to protonate those alcohol functions to make good leaving groups. sulfuric does that better than nitric. I think

>>1397345
Cotton and wool are different materials with different properties, anon. Which do you need? Either? Just something soft and fibrous?

>>1397190
Sulfuric and nitric acid react together to give a compound that stick itself to cellulose, giving nitrocellulose

>>1397399
Oh shit, I mean cotton, I was really tired when I replied "wool"

>>1397405

>>1396904
You can't.
But if you tell us why in hell you need conductive cotton, we might find a replacement you haven't thought of. Is it for a fuse? A detonator?

>>1397423
Doublemint Dave and Mark the mint man are taken. OP is going for the nickname electrified cotton Carl. No other reason, really. He just wants a cool sounding nickname.

>>1397534
Can't you just have a thin copper wire in the center?

>>1397541
How do you get a cool nickname from that?

>>1396927
You're the fucking asshole who makes 'Jamal' jokes. Your day is coming.

>>1396904
Soak it in a solution of high strength nitric acid anon.

Do it.

>>1397857
No, I am Spartacus.

>>1397190
The sulfuric acid is present as a catalyst to produce the nitronium ion, NO+
2. The reaction is first order and proceeds by electrophilic substitution at the C−OH centers of the cellulose.

Just like any nitration in ochem, you plebs

>>1397895
No, its me. Im spartacus

Dry graphite lock lubricant.Yes, I know, I am genius.

Wool is proper for cotton in the raw, such as 'cotton wool,' since op had established he was talking about cotton wool and not sheep or steel wool there is no need to identify the source of the wool.

up the voltage until it conducts

>>1396904
just get hold of some carbon fiber scrap, unweave it until its just fibers and spin it with the cotton.

personally i don't think having electrically conductive cotton is a good idea. to keep its "cotton-ness" would mean if something conductive is added to it while its spun or soaked in something conductive like collodial silver would just be a fire hazard unless its just millijoules.

OP if your thinking about making gloves that work with capacitive touch screens, just buy a cheap pair of gloves, BTW they just weave in something conductive.

Carbon fiber?

>>1398210
No, I am Spartacus!

>>1398280
Pretty much this.

calm your tits Jamal, it's just a joke

Look into conductive polymers. I read a few articles that claim solid state ionics is possible as long as the material is in a tetrahedral formation. The only tetrahedral compounds im aware of are usually sulfates.

>>1397124
Yea. Let's not kill the guy. Are you a sadist...come on!

>>1398273
This. Google up "diy conductive cloth/string" mixing the graphite with ink or dye works for thread. Stays flex but run a signal, sounds like it could work with fluff.
