Man your videos are so helpful, again and again. Best electro-chemistry channel on yt.
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.
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
This has been in my mind for some time, thanks for the video!
This video is helpful in many ways, thankyou :D
Nice video. Have you tested the thermal conductivity of this ?
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
What would you suggest to make it flexible?
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.
Hello! Thank you 😊 They are mostly used for electrodes or bipolar plates for batteries in my case.
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)
I'm making graphene for the first time using Sodium Sulphate, how can I filter the graphene from the final mix?
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
Yes.Nice Job.
Can this be used for electrolysis?
Are you using graphite instead of graphene powder?
THIS VIDEO IS AWESOME!!
Thank you man
How do we use gum instead to make it flexible ?
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
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
Will Printer Toner work?
Would this be stable to bromine for Zn Br2 battery?
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.

it will change GRAPHITE powder to graphine?
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
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.
did the plastic made with graphene show any improvements? Have you looked at this material for bipolar electrodes?
Is a bit better with graphene, yes. Of course I look into bipolar plates,.... that was the plan on the first place.
@@cayrex I look forward to your next video! Thanks for replying
Cool, I will change the steel plates and put those plastics in my HHO generator.
I read Steel produces hexavalent chromium wich is a "turbo" toxic and causes DNA mutation...like radioactivity by the way
Did you have any results with plastic plates in HHO?
hey cayrex2.
I made your grahite plastic and it works very fine . thanks.
gerhard
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 👍
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.
polystyrene is a good binder,... is hydrophobic, have good temperature resistance, can take good load of conductive material with low surface area, etc.
what is this graphite good for??
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
You are fine. In basic you can add MnO2 or something else.
@@cayrex Until now I have not found a catalyst that is safer than MnO2
How about mixing some silicon/silicon dioxide in there?
Thanks for your time
😊😉✌
can you use this in an HHO hydrolysis device for your plates?
Yes
👍
Me queda la inquietud si la prueba de resistencia fué realizada sobre la primera mezcla (Grafito) o la segunda mezcla (Grafito+Grafeno) ?
Graphite + graphene
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.
olsun idare eder
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.
@@cayrex yes I'm taking about the same ! Thankyou for your reply !
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.
Yay science for the poor man!!!
why no nitro thinner like other videos show?
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?
@@cayrex 1600 degrees Celsius. I am casting steel and bronze emblems
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
@cayrex2 how hard and how resistant is this plastic? How many kilos to break it?
Hmm hard to say,.... is hard like polystyrene can be. To make stronger you need to add carbon fibers
@@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.
this materialis real Graphene?. after it dry .It has cohesive and hard ?
A mix of graphite and graphene, purchased from graphene supermarket
have you ever thought of building a microwave plasma torch to make "bulk" quantities of graphene?
can you use it for thermal pad on CPU?
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
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
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
Try sandwiching wire mesh in between it for anodes
Like this th-cam.com/video/KPR9bP6edq0/w-d-xo.html 😉
10:33 Hard time trying to kill the Graphene Plastic Fire Mouse! Jajaja
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
Thanks. Yes you can
Hi, i made your graphite plastic, but there is no reaction of resistance test using voltmeter.
To little graphite? The graphite is not good? You dont press the plastic enough?
Its good for bulettproof vest? Like superhero :D
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 🤔🧐😂
Then you will have like batman armor 🤣
Polycarbons are also good with the mix of carbons/carbon fibers
Can I use it in electrolysis cells?
Yes
@@cayrex Thank you
May God guide you
Do silicone-graphite materials
Sir please tell me the melting point of this product
Around 270 C Look at melting point of polystyrene.
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
How strong is it? Can you break it with your hands?
The first one is really hard to break with the hand. But can be made more stronger also
@@cayrex how strong is it
@@johncarpenter5415 You can break with hand with high force. Adding carbon fibers make more stronger
@@cayrex so what was the point of adding graphene
@@johncarpenter5415 for better conductivity. Is more or less for bipolar end plates in battery systems....
what is the resistance value of it?
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
@@cayrex Thank you for replying. This information is useful to me.
@@merveoguz7453 No problem 😉
is this ok to sit in an electrolyte solution?
In what electrolyte?
@@cayrex most likely NaOH or KOH.
@@carolinecicotte5555 That will be no problem especially below 50% of concentration
@@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?
I cannot get the styrofoam dissolved on the acetone. Any tips?
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
Graphite+baking soda+super glue also works
Hmmm, I dont know why you need baking soda!?
@@cayrex I think the baking soda causes the super glue to instantly harden/cure. The graphite makes the bond many time stronger.
@@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.
@@perfectbudz8430 Yes it is moldable under certain conditions.
@@cayrex your method or the other?
LOVLY
thats not making the plastic, thats recycling it!
☺
Thats not graphene. Graphene is one atom thick. Not like plastic or metal sheet like thick
Of course is one graphene one atom thich. Millions and millions of graphene pieces?
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...:-)
mhm ☺
