Nice video. Have you tested the thermal conductivity of this ?

Cayrex thank you very much for this video and some other once I watched inthe last. I melt aluminum to make skillets. Can I use this plastic inthe interior of my mould Thanks

What would you suggest to make it flexible?

Thank you. I will update you on my test. This was very helpful. I was looking for making the graphene plate but graphene is brittle. you have provided a lovely solution. You truly are a genius. Solutions providers are Geniuses. You are a real genius. Thank you again. For the circuit, we can embed the copper / lead connectors (any shape) so wires can be attached. The connectors will be sturdy. How long did you take to dry the plate?

I'm making graphene for the first time using Sodium Sulphate, how can I filter the graphene from the final mix?

Would this be stable to bromine for Zn Br2 battery?

How would an electrode made of this handle oxidation? I see videos where carbon rods are deteriorated quite quick, but more like crumbling erosion than turning into co2. Is this more stable?

Can this be used for electrolysis?

Yes.Nice Job.

Mix with spatula and then when it become play dough and u can snap it and it’s not sticky is when you can pack into a mold. I use pmma to make dentures. Cool how the polymer process is same on stages of material. I might make a pmma based graphite plastic

How do we use gum instead to make it flexible ?

It would have been useful to have a baseline resistance reading of the graphite for comparison. There must be a point of saturation where the material loses it’s plasticity. It would be interesting to see how low the resistance can be while the material is still plastic.

The graphite plastic have around 108 ohms/□. Yes, right,... you can load the PS with graphite with quite large amount, but way less load you get with activated carbon, for example (the PS lose the plasticty)

Not sure. Maybe. It has quite good temperature conductivity with good load of graphite. If I remember correctly the softening temperature is around 100 deg C

Acetone doesnt actually dissolve PS fully - it just weakends it fast and releases all thengas in the EPS. So can never make a good paint like this. Even saturated with acetone it will always remain a loose putty/like consistency. Quite a few common paint thinner solvents like toluene and xylene can do a full dissolution that could make it paintable or even sprayable (nice for electroplating non-metals). Also benzene (usually sold as brake cleaner) and chloroform are other alternatives. I have not tested the latter myself

@cayrex

Yes correct. Here is no need that the acetone will completely dissolved the PS, because in the end I make it into a hard electrode and not into the ink. If you want to make into the ink, then you will need toluene.

If you mix some metal powder such as copper or aluminum into the mixture. If you then throw the pressed graphite plastic into hydrochloric acid, the metals remaining on the surface will dissolve. Metal powders that cannot be reached by the acid remain in the material and can contribute to conductivity. Also I thought this would increase the surface area of ​​the plastic, what do you think about this? I'm sorry for my bad english.
