Making Graphene Filled Plastic

[@anishmoolchandani]

It's just been a day as a member and I have learned so much in-depth. Thank You, Sir Robert.

[@donaldthiel8379]

I’ve waited years for this video. Thank you.

[@michaelnelson3848]

I know this video is a year old but I was wondering what solvent you would use if you wanted to combine the graphene with HDPE as well as what surface would be inert enough for it to dry on. This is also in regards to a long term project that I'd love if I could get in contact with you for further consultation, again, loved your videos and had to sign up for membership!

[@William_Hada]

Very useful information here Rob. Thanks for sharing.

[@ThinkingandTinkering]

cheers mate

[@quantumenergysolutions9128]

Is that how you made the bullet proof plastic?

[@RahulKumar-nv9cf]

Sir, how to disperse graphene powder in epoxy resin? will this technique work?

[@miainez6566]

I appreciate all you do. Thank you

[@damonhale2873]

Hello Mr. Smith. Thank you for all of your wonderful videos and the time it takes to produce them. The content you provide is valued and appreciated by me and I hope all of your viewers. I have a question for you that might be best asked in a pm. Is there a way to contact you outside of the public forum? I did not see a pm option on your channel home page, perhaps i missed it. If not no worries, again, thank you so very much for all you do and have done! I would love to hear from you. Take care, be safe, and please keep doing what your doing because it's awesome!!

[@preciousplasticph]

If I ran a batch of graphite filled HDPE, In my plastic extrusion machine, would you like to test it on a video?

[@ThinkingandTinkering]

yes mate - absolutely - do you need some master batch?

[@itsknxalpha1988]

I am a member and I can’t find how to make the graphene solution video what is the name of the video please and thank you

[@arechikitsune]

is that one also bullet resistant lol. I wanted to ask if there is a way to integrate graphene into peltier plates by either substituting the ceramics or mixing the ceramics with graphene or doing something else. Maybe make them more efficient at cooling heating etc.

[@ThinkingandTinkering]

an interesting idea mate - I will look into it

[@arechikitsune]

@Hellequin Maskharat what if the outside has an insulated substance applied to it. I forget the name but it’s something that when not available tech you tubers say to use nail polishe instead.

[@hunter8949]

thank you for this video, but i have a question, does it have the conductivity and strength of graphene

[@darkalbertox]

It should

[@pedrojorge4684]

Thank you very much for more of these teachings, if possible, I would like to know if this material made in the video is resistant to corrosion (the typical corrosion in batteries)

[@jasonwitt8619]

Very Flammable with the method Robert just showed.

[@ThinkingandTinkering]

yes it is - so don't smoke over it and don't try it unless you know what you are doing - but acetone wash is a common practice for 3d abs printing so lots of folks know how to handle this

[@jasonwitt8619]

@@ThinkingandTinkering Yes lots of people know about it but just to be on the safe side, LOL ya never know.

[@empiricoxyz]

if you wanted to mix the graphene with epoxy resin, how can you transfer the graphene in water to the resin?

[@MichaelTotin]

I've been trying to replicate this process as I'm interested in reinforcing polyethylene with graphene. The problem I'm having here is that the end product is of low density. I'm assuming as the solvent (acetone) evaporates, since there is nothing else to fill the space left by the solvent, that space is filled with air. My ideas to solve this problem are to slowly add the graphene as the solvent evaporates and finish the process in a degassing chamber to remove the air. I'm also curious what solvent you would recommend for the polyethylene, as others have been asking. I've already tried melting the plastic, but as soon as the graphene is added, it is such a fantastic thermal conductor, that it instantly cools and hardens the plastic.

[@LuisAguilar-xd2hw]

Does this also greatly increase the thermal conductivity of the plastic?

[@schizioposting3176]

Thx Robert this will further our crimal endeavors

[@NoahKainWhittington]

which video in the members area shows how to make the graphene? I would definitely like to experiment with this one.

[@GmanBB]

Brilliant as always, Robert!

[@ThinkingandTinkering]

cheers mate

[@lisakingscott7729]

I presume the tensile strength is improved, not just conductivity? In which case I want a load of graphene loaded filament for my 3D printer ;) Preferably PET or PETG as ABS stinks and shrinks when printing.

[@flashlit123]

Xylene works as a solvent for Styrofoam. Not just melts it like acetone does but actually dissolves it.

[@ThinkingandTinkering]

nice on mate - cheers

[@icghost2]

TY sir! It occurs to me to suggest that zeolite might make an excellent & durable medium for cyclic acetone recovery, at just about any scale. Have you considered polystyrene?

[@doctorpurple5173]

I wonder how graphene plastic fairs as a anode in a electrochemical cell, would it survive corrosive conditions?

[@wanderingzanzey2126]

this obviously depends on the plastic.

[@-robo-]

HDPE might work. It can stand up to a lot on chemicals, except limonene (sp?) Found in lemon and orange peel.

[@doctorpurple5173]

@@wanderingzanzey2126 Teflon is the most inert plastic I can think of, we should try that

[@wanderingzanzey2126]

@@doctorpurple5173 Depending on the chemistry, PTFE is actually a poor performer. It has very poor wetability and actually repels electrolyte. In most chemistries PTFE is used in very very small amounts - about 0.5 - 1% by weight of the whole electrode, for this reason.

[@doctorpurple5173]

@@wanderingzanzey2126 yes but it's poor wetability could be irrelevant if you coat the whole electrode in a graphene layer, then it's the graphene that you have to make wetable and the plastic just has to be conducive and corrosion resistant

[@MichaelSkinner-e9j]

Just out of curiosity, what has your previous career been? Has any company ever had you on tap to oversee any operations, as far as control (electron microscopes), as part of a think tank, or R&D? One of the things about operations is you want to “set and forget” (autopilot) and just look at the “distillate.” After that, it’s a matter of looking at what is being made, testing, etc. Nanomaterials Science is a Beast, but it doesn’t have to be! I just thought scientists and workers would collaborate together, basically with coffee, vegan donuts and breakfast, and trying to make the best stuff Everyone Could Own! These materials would be great in industry (obviously, across the board, besides nanotubes) and Especially Aerospace, with New Industries like VTOLs (manned quadcopters/Cyclorotor Vehicles) and supplying materials to GE for better ranges of Fuel Cells). On top of that, they could help Others like Airbus and Boeing to upgrade their Fleet, and help realize Electric Aircraft utilize a Range of Fuel Cells (SOFC and Hydrogen) What about using graphene/nanotubes to help augment materials firewall materials, besides water cooling/vapor chambers/waste heat generators for said fuel cells in aircraft? What about graphene in Peltier devices for SOFC and firewalls?

[@stemcampprojects7951]

Excellent! This also answers some questions I had about post-processing the graphene in solution. Thanks! leo

[@ThinkingandTinkering]

awesome mate

[@fluffypinkpandas]

@@ThinkingandTinkering Can you run graphene solution in your resin 3d printer?

[@michaellefrapper5863]

Dud, I am a huge fan. One question : If you wanted 1000 kg of Graphene, what would be your preferred/cheapest method? Keep up the great work. 😊

[@jeremynicoletti9060]

What other plastics could this be bonded with? Like HDPE or UHMWPE perhaps? Or are there other interesting ones for different applications?

[@MichaelSkinner-e9j]

Why can’t you increase the concentration of graphene filled plastics? And what happens at a certain threshold?

[@joeglory425]

Heat and extrusion could still work beyond 0.5% graphene loading if the design of the extruder was changed to resemble a positive displacement pump. I haven't done this. I have experience with hydraulics, though, and know double screw type positive displacement pumps can reach 2,000 psi in hydraulic systems and oil like graphene is very lubricating.

[@abdulallam9499]

Hi Robert I am in members area and I cannot find the video you mention about preparing Graphene suspension. Can you please let me know where I can find this in the members area. Thanks

[@michelbisson6645]

i don t see it on your site, but did you ever reproduce Dr Puaharich electroliser patent? did you succeed to understand and used its wave approach the holygrail of water splitting?

[@shazzz_land]

noob question regarding chemistry, could the seringe ideea be applied to silicon glue sticks? can them be hardened a bit?

[@-robo-]

I was thinking about extruding a flexible plastic with a plastic and graphene core. Not a 3D printer, but a purpose built extruder. I have also thought about using a dual extruder 3D printer to print (toy) parts with "wires" embedded in the part. A sort of solid state chassis if you will. Thinking drones here, but also rc boats, cars, etc.

[@ThinkingandTinkering]

nice ideas mate - thanks for sharing

[@billpeiman8973]

"parts with "wires" embedded in the part" Exactly why i have my dual nozzle 3d printer.

[@StrategyYouDidntKnow]

One step closer to 3d printing supercapacitors. Boyan Slat has a project collecting plastic from the ocean that would be a great application for this technology.

Will this plastic perform the same as the one from 4 years ago? Or are they made different on purpose.

[@ezequieladrianminniti6252]

My reflection to this video is: By vacuum filtration you will have graphene and graphite mixed together. You should re-disperse in solvent and then centrifuge to sink graphite and collect transparent graphene supernatant.

Are you going to be showing how to make the plastic filled with graphene from 4 years ago to members only ? I remember you said that you where making it for a company so i thought it was off limits to even ask.

[@joaocarimo]

@Robert Murray-Smith how conductive is this plastic? Can it be used as current collector? If that's viable, you are at one step of automating batteries and super capacitors.

[@ThinkingandTinkering]

that would just depend on you graphene loading mate - but basically it can be used for sure

[@jaredhouston4223]

What could be the purpose of graphene on abs? Does this make the abs stronger? I think it would, if the hexagon lattice of the graphene is kept. Even then if the lattice isn't kept perhaps strength is still added proportional to the graphene amount and the method to coat or dope the abs "ensures" an even distribution. Kind of like adding carbon to iron to strengthen it. Also, a highly conductive electrode could be made with an abs core and a bi-layer graphene coat (ideal) with a CVD method. Loads of stuff to test out, if your ink can maintain an even distribution of carbon in different arrangements of carbon pure structures, I can see that it would be useful in many applications. You could eventually land on one application that could make you famous! Don't stop, keep trying, keep testing!

[@ThinkingandTinkering]

stronger and conductive mate and you are spot on keep experimenting

[@jamesboyddotorg]

You talked about 0.5% graphene being a limit using heat+extrusion method. Any idea how much graphene you can get in using this method?
