Making Aerogel

Hey guys, I haven't posted for a while because it has taken me forever to put this together. I was finally able to make some aerogel! It's also the longest video that I've ever made.


Let me know what you think. Patreon credits will be added in the final version. 

Oh, and this was a charged post, but with the whole COVID stuff, don't AT ALL feel bad if you can't pay for this video. I totally understand that money is tight right now and you should do what is best for you. On my side, things aren't ideal but they're okay and I'll more than survive without Patreon support, especially because this video is going to be sponsored.

But with all that being said, stay safe out there guys!

Incredible work! πŸ‘πŸΌ

with waterglass the precise control of the internal structure is lost, so I guess the result would be quite crappy, more like airy silica gel. But the article is interesting though!

Adam Rak

You outdid yourself here. Great combination of instructive and entertaining.

lol thanks

Thanks!!

Thanks!

Thanks, I am!

Interesting!

It is kind of like silica gel. It was like glass rice crispies.

Nile Red

Thanks!

Correct. Also, the TMOS gel apparently has larger pores and is less prone to cracking during drying.

It's possible, though much more arduous than supercritical drying. Check out this paper, which reports densities down to about 0.1g/cc: https://doi.org/10.1016/j.jnoncrysol.2018.09.049 (sorry about the paywall) Edit: also, they used MTMS for that paper, not TMOS. I still think it should be possible, but it might be harder with water glass.

TMOS hydrolyzes more rapidly than TEOS, so the sol prep step can be carried out with fewer ingredients. The hydrolysis of TEOS typically requires a catalyst to make it work properly (aerogel.org recommends ammonium fluoride).

I have tried and succeeded at gelling up water glass, but I do not have a supercritical chamber. Is it possible to make aerogel from gelled water glass? Or the density would be much less than what we consider aerogel, and more like silica gel?

very good video, with lots of interesting details! One of the best I have seen on aerogel, it was well worth the work you have put into it. When you have air dried the gel, you got silica gel, right? It looked and fizzled like very airy silica gel.

Adam Rak

Congrats! Looks so cool, you should be proud! :)

I wouldn't dream of withdrawing my support. Especially now.

Amazing and congratulations! Your projects have constantly been an inspiration to me and seeing the amount of work and research that was put into this really puts into perspective how impressive the final result came out to be.

what are the advantages of using TMOS over using TEOS?

David Pelayo

Wow! Congratulations! Nice job!

Michael Aichlmayr

Congrats! That was fantastic!

a true legend

Well worth the wait and hard workβ€”congratulations!
