"Smaller graphite particles have a higher surface area-to-volume ratio, which increases the rate of sulfate ion adsorption on the surface. However, the increased surface area also means that there are more lattice defects on the surface, which can act as barriers to the diffusion of sulfate ions into the interior of the particles. As a result, intercalation of smaller graphite particles typically requires a higher temperature and a longer reaction time in order to overcome these barriers and achieve a complete intercalation. In contrast, larger graphite particles have a lower surface area-to-volume ratio, which decreases the rate of sulfate ion adsorption on the surface. However, the lower surface area also means that there are fewer lattice defects on the surface, which can act as barriers to the diffusion of sulfate ions. As a result, intercalation of larger graphite particles can typically be achieved at a lower temperature and a shorter reaction time." - ChatGPT

I worked for the British Ministry of Defence. I did some crude tests on 'fire retardent foam', the sort that is used in furniture. I was VERY disapointed. Believe it or not wool as in felt was by far the best. So, a challenge for you - find a better fire retardent soft covering / filling better than wool.

If you want to go the water-containing chemical route, you might try saturating the wool or felt in a solution of water and Epsom salt, aka Magnesium Sulfate Heptahydrate, then letting the product dry. Each molecule of the salt has 7 water molecules attached, which would make it take quite a bit of energy to heat it up. Epsom salt does decay at high temperatures, but it does so by letting go of water molecules one by one, which might even displace oxygen at the site of the fire. Add in layers of intumescent material, and you might have something that is effectively fireproof. Or, you might not. I'm not a chemist, just someone who's watched a lot of Nile Red.

"Dig my credentials, am I retarded or a lier?" Some idiot online... Both, ether, not important. Welcome to the internet.

I work in construction, doing telecom, and I’ve used the red putty in the video a good amount. it’s worth mentioning, that the putty has a really different application than the fireproofing paint. we use putty to stop up the sleeves we use if we need to run cable through a wall, or inside an electrical box, for other applications like sealing, they use a caulk that cures hard. the putty, at least to my understanding, only needs to stop smoke getting between rooms, or, say the insulation of your cables catches fire, to stop it using the data network to spread fire throughout the whole building, I’d be interested to see how the putty reacts when heat is applied to it while it’s inside a confined space, pack some into the end of a 1” pipe or something. I dunno if the results would be different, but they might be.

Great video as ever. I did think this sort of expanding fire putty stuff was put around pipes and electrical systems, allowing them to move, but in the event of a fire, the material expanded filling any gaps and therefore stopping the spread of the fire from room to room.

You never cease to amaze. Outstanding research and topics. Thank you 🙏 ❤

I work with the IBEW and often use various fire proofing products. The important thing to remember about commercial fire proofing is that they all have a time rating. So perhaps the puddy with graphite flakes are good for 1 hour while the carbon foam paint is good for a longer exposure time.

Awesome Video! Graphite is a really interesting material. I first learned about its intercallation property a couple of years ago when i was experimenting with dual-carbon intercallation cells as an alternative to traditional battery cells

I am a fire alarm technician. The NEC requires fire putty on any sleeve passing through a firewall. Bearing that in mind it is applied from both sides of the entry and exit point. The small flakes in the fire putty are meant to expand and drive the putty further in towards the center of the wall and also outwards towards the center of the room. Thus it compresses and seals the point from fire being able to penetrate from one side of the wall to the other.

I'm always excited when one of your videos come out! Keep up the amazing work!

The smaller mesh taking longer may have something to do with surface tension. It may also have something to do with a reduction in the capillary effect. Just a thought.

Or smaller flakes have more edge. 4 circles with a diameter of 1 have the same area (and with the same thickness, mass) as one circle with diameter 2, but the four smaller circles have edges with an overall length of 4pi, whereas the bigger circle has an edge with a length of 2pi. And since this reaction happens on the edge of the flakes, more edge means more reaction.

Yeah, if it was just "more edge speeds up the reaction" it would have been obvious and not commented on. The actual result which is reversed implies that the reaction which opens the edge is a lot slower than the intercalation itself, which completes rapidly even if it has to cover a large surface area.

@absalomdraconis

Жыл бұрын

Supposing that the opening _is_ the restraining factor, then the reduced number of atoms on the edge may also be a factor: if the intercalation is sufficiently faster, then it would imply that the opening of the edge is dominated by random chance as much as anything else, with the result that "rolling more dice" is the most effective way to speed things up.

Excellent video as always! There seem to be lots of interesting further experiments to do with the various practical applications of the expanded graphite, though at the moment I am drawing a blank. But I'll look forward to the next video no matter what the topic may be, keep up the good work!

Nicely done! A great video to introduce to intercalated graphite. If you want to go a bit further, you can actually produce high quality graphene via the modified Hummer's method, which is just a few steps further. You would need some h2o2 in your water and hydrazine as accelerator, but then make sure that the quantity is small, you have a ice chunks surrounding your Erlenmeyer flask and and extra cover (fume hood is possible). Cleaning and recovering the graphene is the most tedious step, using a roto evaporator and centrifuge at least 4-5 times. Thanks again for the video, it does bring me back 10-12 years, when I was working on nano sensors during my PhD.

New NighthawkinLight!!! Such a very cool project and deep dive into the topic!! My mind is already spinning with ideas and questions 😁🤯

I have a hypothesis about why the finer-grain graphite was more difficult to react: While the stoichiometry is the same (1g coarse graphite, 1g fine graphite), and while reaction rate is typically proportional to surface area, of which the fine-grain has more, in this case, it's the completion of the reaction that we're looking for, and with more surface area to react, it just takes longer (for the same concentration of acid and nitrate). I think of you used more acid and nitrate in proportion to the increased surface area, the reaction would proceed at a rate more similar to the coarse graphite. Would love to see this tested.

@barcodenosebleed5485

Жыл бұрын

Kinda along the lines I was thinking. Once you pop open a layer on the coarse grain, it's open. A lot more total layer popping needs to happen with smaller particles.

I think the smaller mesh takes longer because of the reaction first taking place on the edge of the flakes. For the same amount of flakes, yes it'll be faster for the smaller ones, but for the same amount of mass, there will be a lot more small flakes and a lot more molecules that are the working edge

Dude, your presentation skills are top notch! 🤙

Good ol Six. Is there anything it cannot do?

"Self extinguishing" is commonly used in fireproof materials. They contain chemicals which block combustion, but are locked either mechanically or chemically inside the material until the initial flame releases them. That way the material retains it's flame retardant properties for a long time at normal temperatures even if ordinarily they'd slowly diffuse away.

The quality of your videography is top notch and the content is outstanding too. Keep up the good work.

An absolute must watch for science interested people. Thanks for the Knowledge

I wonder if the putty is more designed to rely on the expansion of internal particles? Those might cause the putty to swell a little, allowing it to seal any small gaps that might remain from installation. Mixing in particles will always result in some on the surface (just like a chocolate chip cookie), and these may not add much, but you'd get some particles contained within the putty applying force to it.
