I remember ol mate kev said that using small and large size graphene gave best results and from my experiments it does seem to work very well with 5 and 35 mesh.
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?
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
hello, my friend, I have a little problem, I couldn't make this conductive paint completely, when I mix carbon powder, graphene powder and sodium silicate, it becomes mud, but like you, how can I make a fluid paint, how much should I mix it, can you help me by the way, your videos are very good
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)
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?
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
This is so awesome man! Do you mind letting me know what type of Graphite this is? I have been trying for ages to replicate this and mine comes with heaps of bubbles and has no where near this conductivity.

Hi..this is the first time watching your content, awesome!! You have a new subscriber! 😊Its fascinating watching live chemistry! What practical uses are there for this material, could you kindly make some videos of its potential uses? Would be really interesting.
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.
polystyrene is a good binder,... is hydrophobic, have good temperature resistance, can take good load of conductive material with low surface area, etc.
Hello sir, very interesting video. Is this way we can add a catalyst, for example MnO2, or can we make the catalyst separately (also using Styrofoam) and then glue it together? Sorry if my language is not understood
I think you are right Maybe it can use solve carbon powder with aceton maybe we ll give us bettet results I'll try it and i'll give you results Thx for video
The first graphite mold I had was CNC cut. The 2nd was made of clay and graphite but I don't know the process as same was delivered to me as an already mix dow. I only had to compress it with hydraulic press to make the mold and put it in an oven for 2 hours
can i use this material for electrodes? I was thinking of using your material for electrolysis. i want to make the electrodes from the mixture that you made. Nice video btw
If you use only this one, not really. Composite material from layers of kevlar fibers and ABS / carbon mix of graphene and or carbon fibers to strength the plastic. Then maybe will work and you will survive 🤔🧐😂
@@cayrex I think intercalated and expanded graphite or graphene would probably make is way stronger as Graphene is at least 200 times stronger than steel. When compressed it might make it stronger. The issue is to mixca high concentration of graphene or graphite. Probably a bit or resin would give the stiffness.
Depends on how is made,.... how much conductive material is used, how much is pressed,... the surface resistance which I get with hand made variants is 20 to 4 ohms per square
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
@@cayrex amazing! thank you so much. another question for you, even though it may be a little silly but is this /could this be essentially the “air cathode” for a zinc air battery?
@@cayrex but your graphite plastic is moldable. The instant hardening effect of graphite+baking soda+super glue that I've seen is good in molded objects and quick repairs. Like filling holes and copying objects using molds.
The styrofoam will not completely dissolve in acetone. You get something like slime like product. But if you are not able to dissolve the styrofoam to that point,... make sure you are using real acetone
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
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.
is not graphene......is graphite reinforced plastics.......graphene is a 2d material his thicknes is the diameter of carbon atom ....apologise my critics but the material science is not cryptonite chemical...:-)

Nice video. Have you tested the thermal conductivity of this ?
Very straightfoward! Thanks for the remake.
Very interesting but I would have liked to see the difference with and without the graphene, what was the difference in ohms. Cheers John

can you use this in an HHO hydrolysis device for your plates?
Yes
Nice results :-)
Was the plastic you tested (13R6 Square), the one with added graphene?
Also what was the resistance in the Z plane?
Thanks - Martin.
Yes, that was the plastic filed with graphene/graphite in ratio1:10. The resistance of Z was similat to the resistance of □ measurements.
But like I say,... the resistance is depending on the amount of conductive material, type of material and in the end the pressing force
Are you using graphite instead of graphene powder?
hey cayrex2.
I made your grahite plastic and it works very fine . thanks.

Nice man. Good work 👍
@@cayrex thanks. Helped me a lot
@@ehochimalpi next time you can make a hole to the zinc and conect the wire. And on the end you put the conductive plastic.
@@cayrex 👍
Will Printer Toner work?
it will change GRAPHITE powder to graphine?
Nice. But it is more Simple just mix it with Good polymers and let it dry. Any way I do exfoliiate with H202 and later use gravity to self assemble.

Me queda la inquietud si la prueba de resistencia fué realizada sobre la primera mezcla (Grafito) o la segunda mezcla (Grafito+Grafeno) ?
Graphite + graphene
Hi there
Do you have an idea of what is its tensile strength
And if not how strong do you think it is?
It will be less than natural polystyrene. The acetone causes embrittlement.
How about mixing some silicon/silicon dioxide in there?
I'm making graphene for the first time using Sodium Sulphate, how can I filter the graphene from the final mix?
Yay science for the poor man!!!
Just make one, how long need to press it? will try to use it as current collector. thanks master for the idea.
From 2 to 4 days will be good. The plates need to be fully dry
@@cayrex just open it, its ok, its dry already.
what is this graphite good for??
have you ever thought of building a microwave plasma torch to make "bulk" quantities of graphene?
Thanks for your time
😊😉✌
It can used as patch for reparing damaged tire with small hole?
Huh, I dont know. I think not,.... but you can try it
@@cayrex i think it can react with carbon of tire with thermal reaction
@@hamzd1951 You need to know that the polystyrene will be hard and not flexible. But like I said,.... you can try. And let me know

Thx for video
What would you advise me to use to bond graphite powder to make a high temperature mold?
Clay
@@cayrex clay + graphite powder only? Isn't there any liquid to use as binder? I would be grateful if you could please explain it to me. Thank you.
@@odeltarkhan3033 The clay can do the job,.... clay, a bit of water and graphite. What temperature?

I was wondering what is the product that you use for the graphite powder and where you can get it from ?
synthetic or natural graphite powder 50 microns. You can find this graphite powder on the internet, like ebay, etc
THIS VIDEO IS AWESOME!!
Thank you man
this materialis real Graphene?. after it dry .It has cohesive and hard ?

How do we use gum instead to make it flexible ?
Would this be stable to bromine for Zn Br2 battery?
Hey can we use graphite rod powder found in dry cell batteries ? And is it the same material that you use in you Al air batteries ??
You mean powder made out from graphite rod from zinc carbon battery!? So, if you dont have other,.... will be this better that nothing.

Do silicone-graphite materials
Graphit ? + acetone + styrofoam ??,
Or carbon only ?,
Correctly. Styrofoam and acetone first,.... and then you add grahite or other conductove materials
To make styrofoam into more liquid, you can use a bit of nitro thinner
why no nitro thinner like other videos show?
