Surely I can’t be the only one who thought this were interleaved DNA chains
Anecdotal evidence would seem to suggest that DNA is not a particularly effective armor.
I skimmed the article, scrolled down but people hasn’t mentioned its mechanically Chain mail in atomic scale yet? Did I read it wrong?
Of course it’s plastic.
it’s very lightweight though, so it could reduce plastic usage by mass, by reinforcing plastic/other materials.
There’s also no reason why polymers need to be made out of oil: See PLA, cellophane, viscose, etc.
I mean, we have tried to completely stop, or at least slow, the refinement of crude oil, because there’s so much fucking byproduct that is made from it and is subsequently recycled and converted into plastic. What else can we do with all that fucked up petroleum byproduct besides make it all into some form of usable plastic?
I’m sure it will mix well with the depleted uranium smoke the targeted crew will already be breathing.
Microplastic, even
Whether or not it’s plastic isn’t as big an issue as whether or not it’s biodegradable within a realistic timeframe.
everything is degradable with enough heat
Could this be used to make a space elevator?
It would probably be strong enough, but not viable to manufacture.
“the manufacturing process of the 2D polymer is highly scalable”
First line of the article
Ok but there’s ‘high’ and then there’s ‘low earth orbit’.
That’s what my dispensary tells me too
My man!
Extreme doubt on strong enough. The author of this article barely understands the words they are using. Cool it strain hardens, so do so many other materials. Cool it’s tough like many other materials. Wow it has more links than others. No actual numbers about toughness, yield, ultimate strength, cycle limits, etc. It’s great research, but it absolutely isn’t going to magically solve the space elevator issue.
Space elevator companies seem to think that materials exist that are strong enough, just that they are not long enough.

Very much layman conjecture, but my assumption is that this material is stronger than carbon nanotubes and graphene.
Any company will market that its ideas are possible. The article you linked is promising, but take it with a huge grain of salt. They are moving the goalposts the whole article. Flat graphene is a great material for space elevators, but it can’t currently be created without defects. Polycrystaline means the graphene created includes defects sort of. It means the graphene they created that is km’s long has shitloads of places where cycle loading will cause it to fail way under (like 10%) of its expected load carrying capacity.
No.
What about a space escalator?
I heard it was for lifts only
Escalator is smart, because if it breaks, you can still walk to space.
I think I remember reading that a structure strong enough would have to be wider than the earth
The stronger the material the thinner it could be.
There are a lot of properties in the word ‘stronger’ though.
China, please respect this secret. Its made up with grapheme threads. Its impossible to understand exactly so we made a little picture with the molecules and such so you can’t copy it.
Why don’t they just use diamond, the hardest metal?
Hardness isn’t the best thing to have in armor. In fact, extreme hardness means extreme brittleness.
Tensile strength is more desirable in armor. That’s the sort of strength that a string or rope, or Kevlar will have.
Those can stretch a bit before breaking.
Kevlar will stretch a bit when catching a bullet, this does a few things, but importantly it slows the bullet before stopping it.
So this new material will likely show extreme tensile strength rather than hardness.
I thought Dragonforce was the hardest metal known to man?
100 trillion barry bonds
At least it’s not 100 trillion James Bonds.
i could make stronger
Me when the only thing I eat all day is weed and cheese.
I did your mom stronger
Goes on to form company called General Products, builds spacecraft hulls. 😉
Please, could we move to Known Space?
I can’t wait to find out how toxic this is.
They will make it into a mandatory dress uniform for school children.
Good news, it’s completely non toxic.
Bad news, it costs 2 million dollars per square foot.
The pentagon will now take your whole paycheck.
Thank you for your support, patriot.
The article says the process is scalable.
Good news, it costs 2 million dollars per square foot, so they won’t militarise the police further with it.
There is an old Russian joke.
Son asks his father, “Daddy, I’ve heard the price of vodka went up, does it mean you will be drinking less?”, and the father answers “No, son, you will be eating less”.Well not immediately… Years from now when the military develops something even better then this will all become surplus and sold off to SWAT teams etc. for next to nothing.
With these bonds so dense, I want to imagine that it would actually be quite non-toxic as these is little to react with.
Then again, I’m not a bio chemist
…and uses it to oppress and/or disenfranchise poor people
America bad
You mispronounced promote American interests.

hello I would like to order a thousand full plate mails
I’ll be eager to know what the results will be about it’s resistance to bullets and sharpened objects.
Currently, garbage. They used it to reinforce a polymer to go from a strength of 50 MPa to 70 MPa. Kevlar is 10x stronger, commercially scaled, and cheap
