Affray
You are correct, it is very cool.

I really want to see graphene be used in computer heatsinks since its such a good conductor of heat.
bacchuss
Can't do it my self but I'll be mad if no one puts the bender neat up
Milchsteak
So it is really light, or is it just really thin "bubbles" filled with air?
AnonOmis1000
LEAST DENSE!!!
kno3cs02631415
When saying a material is light when not refering to amount, it generally implies less dense-- especially in layman's terms

Plot twist - it's the worlds strongest flower
wuzzyvear
Crap! Didn't read the comments all the way down. You beat me to it! +1
wuzzyvear
Plot twist: That's a hefty stone and the flower is genetically modified for super strength and durability.

I was beat to this comment. :(

Solid is not a good description of an open cell foam @op.

Graphene is also incredibly durable as I recall

There's that word again, heavy. Why are things so heavy in the future?
CloD0
if it was lighter than air, wouldn it it float like helium?
TheMajesticHarpyEagle
Lightest solid, not lightest substance.
CloD0
The article linked says 7 times lighter than air
TheMajesticHarpyEagle
Incorrect.
CloD0
That was my point ;)

graphene is one monolayer thick carbon. im not an expert, but my approximation is that this is more than one atom thick, thus not graphene.
creamedLead
I think this is called graphene because the sheets were layered in such a way that they aren't structurally the same as graphite, but IDK
perceptualmotion
nah, graphene is made from graphite by peeling it off. i also happen to know they have the exact same structure.
Esarai
That's mistaking the tree for the forest. It's not one contiguous sheet, it's made of smaller graphene sheets randomly arranged.
perceptualmotion
yes, problem is that we already have a name for that, its called graphite or carbon. this is like calling windows sand grains. its dumb.
Esarai
Graphite isn't all graphene flakes, though. Yes it's carbon, yes it has graphene in it. This semantic pedantry is what's dumb.
perceptualmotion
what do you mean graphite isnt all graphene flakes? its not pendatry or semantic, it is a definition. stupid hype.
Esarai
Huh, I should have fact-checked myself. You're right, I was mistaken. That means this is basically foamed graphite.
Yacobs21
It isn't just graphene, it's called graphene aerogel because it is made up of graphene that is supported by carbon nano-tubes

cousteau
If it's lighter than air why doesn't it float like a helium balloon?
Yacobs21
Idk, probably whoever wrote the article was exaggerating
cousteau
Maybe if you remove the air from inside it it's lighter, but it naturally has air in it (air is about 1.3 kg/m3 and this said 0.160 kg/m3)

So... the antithesis of OP's Mom?

So the heaviest gaseous substance in existence.

wait there's something heavier than Osmium, but that will crumble under less than 4 g/cm²? holy shit.

How strong is this stuff?

Asking the real questions

Judging from the picture, it's at least strong enough to keep a flower from floating away.

Mom uses to work for museum, got a shipment of a small amount, broke it in first 30 mins
Creyton
Is that why she no longer works at the museum?
AngelRick
Unless you do some serious geometric wizardry, graphene is very anisotropic.
theshells
In general is it very strong stuff tho, or not so much?
AngelRick
Yes. Graphene has a very high ultimate tensile strength. Orders of magnitude higher than most materials.
AngelRick
I.e. It's material properties will vary depending on your stress tensors.
cousteau
What about, uh, amorphous graphene aerogel? (Is that a thing?)
AngelRick
While I have some training in the subject, I am by no means an expert.
AngelRick
Great question! On the microscale, graphene will retain its structure, but on the mesoscale can might be configured differently for 3-D.
1metalnation
high compression strength, low sheer strength, it's very brittle
BESTtaylorINAUSTRALIA
It's not brittle it can be squeezed down to a 10th of its self and reform again
1metalnation
The hell do you think "compression" means?
Bubblesmakemehappy
I used to have a bunch, it's crazy brittle.
MLGsamantha
Are you sure it was graphene aerogel? or was it some other kind? Cause Silica aerogel is super brittle, it's made of the same stuff glass is
shimmernshine
Why did you have a bunch of graphene aerogel, and what happened to it?
ff36
Compressed it down to a tenth of its size then lost the damn thing
SirSage
Somebody better tell me whether this shit is brittle or not before I shank a bitch with sharpened peanut brittle
LacquerHead
It's friable, technically not the same thing as brittle but pretty close.
1metalnation
If you try to flatten it, it'll be fine, if you grab by the top and bottom and twist, it'll break, cuz it's brittle
LSKG
strong enough that if you layer it in a weird shape it it's so strong we can build a space tower and plans are in motion for that, 1
z3lfmoord
Plans are not in motion, it's merely an idea
LSKG
i mean a bunch of rich people are talking about it, location, logistics, anything that can point to a certainty of construction not done yet

the problem is making enough of it, in this shape https://www.fastcodesign.com/3066988/mit-invented-the-material-well-need-to-build-in-space

*least dense.

Doesn't calling it light when refering to type imply low density?
