Rob, I'm a member of your channel and I have two questions for you. 1. Can the conductive plastic you described be used as the carbon coating of the negative plate of a ultra-battery. 2. And can it be used to protect the power collector in the zinc-bromide battery. Thank you for your answers. I'm beginning to to love the quarantine, because it has put you into MAD SCIENTIST mode and we are getting ,bunches and bunches of outstanding video's. Thank you, sir.

I have it in my head that carbon nanofibres can make conductive plastic in a smaller ratio because the longer conductive fibres contact each other more readily than graphite. Also, those black plastic bags used for electronic parts are quite conductive too, already mixed in a nice flexible plastic. They are sometimes repurposed as sensors because their resistance changes when stretched or as flat conductive sheets for x-y sensing. Lots of conductive plastic around, just a pity no one uses it for vacuum cleaner hoses to make them anti static. Great video Robert.

Hey Rob; I'm attempting to use ABS and Acetone to make a conductive plastic. I've used 30% by weight of graphite powder and I'm not sure the best way to ensure that the coating is conductive at all. I've coated some copper foil in the plastic mix and not able to get a conductivity reading from the multi meter. I assume I'm doing something wrong; Any pointers? I've used 70 grams of ABS in 200mL of acetone. I've been inspired to create some Zinc Bromide batteries at home. Thank you for the great content!

honestly this really has opened up a new world. I had no idea you could decompose plastics into solvent s and then when the solvents evaporated the plastics would reconstitute. Immediately makes me think of mixing small ceramic, sand or steel particles to make a abrasion resistant plastic paint. or dipping regular cardboard in it to make some cheap pastic strucutre with recycled plastic. also what if you left the plastic as insulating (no graphite) and instead mixed mica or metal flakes or chips in it to make basically solid state strange capacitor! slap a metal collector on each side... Please try this if you run out of projects! I have been saving lots of plastic soda bottles and milk jugs for some reason. Got any idea what solvent would dissolve them? I have some acetone. how would I recognize a plastic that acetone would dissolve? this really is an eye opener for me. I once tried to use heat to melt milk jug plastic and that is very tricky. This is fantastic.

Hey Robert, I was wondering why is polycarbonate in your video in a liquid syrup state? Have you melted it down to temp higher than 60°c? Till now I've only encountered solid bead PCL. Also, I wanna tell you that I wanted to buy some carbon-filled HDPE from your website but it's out of stock. Could you help me with that material cause I'm working on graphite electrodes and I want a premium quality conductive plastic to run the test?

Greetings. Im woondering if there is an ideal solvent to disolves PBC pipe and mix in some graphite and use it as a conducive coating that's very well bonded with the PVC.

Hi All, As filled HDPE is still not available, I'm trying to make my own waterproof conductive material with either plastic or other binders. I do get good results on the multimeter, but once in use in water based batteries, they fail to deliver current. I'm now looking into surface treatment of the conductive coatings (using Sodium dichloroisocyanurate as oxidizer). This does improve the behaviour, but still significant below that of carbon rods (from pencils). Any experience or advise?

Having trouble wondering why you'd bother messing about dissolving plastic in nasty chemicals when you could, I suspect,. get as good a result by using an epoxy or polyester resin. About the only plus I can see is that, depending on how you evaporate off the solvent, you get a slightly foamy plastic, but if that's what you want, why not use a foaming resin instead? I mean, if it's all you've got, sure. Oh, and for the love of god, man, take the chuck key out of your lathe chuck :)

@zylascope

I think epoxy would work. But I wouldn't want it to be foamy. The bubbles could make holes that let an electrolyte in to attack the metal current collector. And I wonder why Rob doesn't use Acetone as the solvent for Poly Caprolactone? I'm sure I've tried that and it does dissolve it.
