And thank you for the link to the cool turn-of-the-century book on casein. Wow. To think, how many lifetimes of experience went into that single compilation. And how it is practically lost to general common knowledge of the tinkering public. Thanks for opening casein back up as an alternative to toxic, smelly petroleum materials.

Wow Thnx Robert.. Never seen this until today !!

I've got to make this thicker! For use in making guitar picks!

So the ammonia (or other alkali) doesn't prevent the casein from setting? Is that because it evaporates as well? If one used sodium bicarbonate, would it leave a residue?

I have a question as someone who isn't a chemist without much access to chemicals. I'm looking to make some galalith that's somewhat clear in a tortoiseshell pattern for guitar picks. How would I pull this off?

I'm working with carbon printing process (I think your brother does that too) and this tip is very very very useful. I will experiment along your lines. By the way, today I've published a video on my channel how I'm doing my carbon prints. With the help of your videos I'm inspired to see carbon print process as something that is not a word of god, but something it could be pimped up, make it better... Your videos are very inspiring, thank you.

Hey Rob, I am looking to make a thin (PEM) membrane material as the heart of my experimental fuel cell and will be adding Mica as the proton carrier. I assume you can just add glycerin or sulphur to make it slightly rubbery but my question is around how you where able to cast it so thin and so accurately?

@ThinkingandTinkering

there is a linear relationship between percentage of solid against percentage of carriers - if you cast a 100 micron film with 35% solids it will dry to 35 microns - you can use that to manipulate film thickness

Thank you so much for the video. I bought the book and was looking for how many parts alkali to add to the casein in order to dissolve it. Does the solution just turn clear when its fully dissolved? I wanted to add sodium bicarbonate instead as an alkali and was just wondering if that would not work as well as ammonia. Also, could a similar process be used with whey protein?

@ThinkingandTinkering

9 жыл бұрын

kind of a clear very slightly amber and carbonates work well too - though sodium carbonate - washing soda - would be better. Whey protein is going to be slightly different - it's going to take you a while to get to grips with casein so if i were you i would concentrate on that - get it up and running then turn your attention to other materials - that's just a suggestion though

Hello sir!, Im very interested in bioplastics, already have been trying with starch and cross linking it with citric acid to try to get a waterproof cloth. (just wanted to see if I could avoid using casein).I tried using tea and it didn't work lol. Big amounts of citric acid seems to be the best so far. I wonder if soy protein could replace milk??? And cross link it with tannic acid or tea??? Also, I would like to buy your casein bioplastics book, but the link seems to be broken. Thank you again for your channel!!! Have a good day!

Do you know if there's a way to use Casein in the context of 3d Printers?, since it's a thermoset instead of a themoplastic I think it can't be re-melted once it's set and most printers work via a spindle of prior extruded material. If there was a way to optically cure it once a layer of it was put down that might be one way, or keep it in a state where it was thick enough to "print" without setting prior to printing that might be another way

@ThinkingandTinkering

I don't think you will be able to get it to do that mate - solvent casting might be a way forward but still a challenge - it can be optically cured but optical curing involves some pretty harsh photo initiators and cross linkers

Sir i want to add copper nano into my bioplastic into my project but i am confused how to go ...i m phd student plz suggest me

Have you tried adding anything like over the counter water suspended acrylic like a concrete sealer to experiment with various properties? I am hoping before long to also experiment with refining and playing around with pine tree rosins with those items like toll oil, although at this point I know nothing about them chemically, I grew up playing with it as it makes a very interesting ultra thin film when reacting with water directly from a fresh young candela* [a word I grew up with and which I can not find on an internet search so I do not know if it is a proper term] when dropped in water. The reaction is rather exuberant and will propel the piece of pine across the water like a little motor although it often twirls and seldom goes straight, and most of the propulsion is from water tension and drag than from anything you would cal real thrust and it leaves a super fine film which can some times be carefully lifted out, although it breaks easily, and it can float a pin on occasion, if you can lay the pin on it carefully enough. I know that amber is the product of resins but not if its anything useful for creating working plastics. Any types of other natural materials one can add would be interesting. If I have any success, I will be sure and post the results where it can be found on my account.

Hi Robert, first of all, thanks so much for the data, love your video! I truly do. I've been watching your casein ones so many times for a design university project, I'm trying to make an MDF-ish type of material using casein as a binding substance. I have two main question, what's the difference of using borax or alkali in the mixture and the second one is if there's an effective formaldehyde replacement (commercially available). I can't find a clear answer in google scholar. Thanks again!

I just experimented a bit with Casein glue. I used CaOH and Calcium Caseinate. The mixture gels up and does not dissolve in water. When i put it in tannic acid there was a very clear reaction with the tannic acid (it stained the gelled up glue and i wasn't able to wash it off). So my guess is that there's some cross linking going on. Maybe this will harden your material. I made some leather before and what happend when i put the dried casein glue into tannic acid felt a lot like what happened when i vegetable tanned leather.

Are there any alternatives to formaldehyde? I would want to use it, but I'm doing a science fair project and formaldehyde is banned.

Robert Murray-Smith It's conductive and that's pretty good! I've mixed graphite with melted PE. I didn't get a nice pretty sheet and it wasn't conductive. In my application I'd be using the conductivity from the top of the sheet to the bottom of the sheet rather than along the plane of the sheet.

Joseph Richardson might well be the way to go - if you are using an acid electrolyte you probably wouldn't need the formaldehyde step as casein is insoluble in weak acid

Corn Starch is what I use, really any starch will work. . just to keep it Bio. I never tried formaldehyde? This would make it a non Bio film correct? I been thinking of trying to carbon fiber some of these materials? Drawl them down as far as possible, to align the links, then 3 step heat treatments to see if this is something that can be done at home. I imagine a carbon fiber made out of natural ingredients instead of The Poly Acrylics would have some interest. Nice information for me these last couple of Videos. Rock on Robert! Peace Out Murf!

lol - no worries mate - but adding formaldehyde wouldn't ruin the bio usp - bio refers to the source of monomer - anyway formaldehyde is naturally occurring in apples etc and is completely biodegradable - if you don't like the name formaldehyde your allowed to call it methelyne glycol if it is in water and normally it is - it's a protein cross linker so no good for starches which are polysaccharides.

This reminded me of petition that called dihydrogen monoxide (DHMO) to be regulated, labeled as hazardous, or banned, because Dihydrogen monoxide: *is also known as hydroxyl acid, and is the major component of acid rain. *contributes to the "greenhouse effect". *may cause severe burns. *contributes to the erosion of our natural landscape. *accelerates corrosion and rusting of many metals. *may cause electrical failures and decreased effectiveness of automobile brakes. *has been found in excised tumors of terminal cancer patients. Despite the danger, dihydrogen monoxide is often used: *as an industrial solvent and coolant. *in nuclear power plants. *in the production of Styrofoam. *as a fire retardant. *in many forms of cruel animal research. *in the distribution of pesticides. Even after washing, produce remains contaminated by this chemical. *as an additive in certain "junk-foods" and other food products.
