New Carbon-based Paper Stronger Than Nanotubes
LynnwoodRooster writes "Science Magazine reports that a group from Northwestern University in Illinois has a new process for creating carbon-based paper that's stronger than nanotubes, and incredibly easy to use to make sheets of any desired sizes. Huge implications for aircraft, automobiles, and the ever-sought-after space elevator?"
yes, but is it smoke-able?
Freaky Schitt always happens to me... WHY God WHY!!
Now try claiming your dog ate your homework!
I hate printers.
I'd hate to see the kind of paper cut you could get from that thing.

TFA states that water is the "kryptonite" of the superstrong paper. Doesn't that kill its practicality in things like planes and automobiles? If it rains, then you could have a major catastrophe on your hands...
My sig is permanently on strike.
You don't expect the _author_ to read it, do you now? That would be insane (for the both of you).
Just imagine what Yomiko Readman could do with that paper!

A run through the laminator should take care of that problem.
Strange things are afoot at the Circle-K.
I thought they are made up of Carbon, too...
Coat it in teflon. Teflon stretches very easily and is water tight.
Any sufficiently advanced influence is indistinguishable from control.
Those nice folks at Enron would have had to resort to magic trying to shred all that evidence, or better to get a carbon based document shredder.
I would think the material would be used for whatever's at the top of the space elevator. In space, it would be safe from water. Of course, accidents happen and that's when you add protection where you need it.
maybe now we can put important documents on paper that can't be so easily and convienantly shredded by (unamed) corporation.
Otacon, my new cardboard box is ready.
Sadly, no. TFA links to the actual paper. Tensile strength is on the order of 35 GPa. We'd need 65 GPa or more from a material with density similar to graphite.
Naturally, then, the next goal is to produce a material that's stronger than paper.

Now to make people look foolish by challenging them to break out of a wet paper bag!
. . . of toilet paper that can't stand up to the vigorous wiping of cyborgs, kryptonians, and super-muscled mutants.
About the water immersion problem, why not make the sheets like newspaper paper? By using giant rollers. As the Nano-paper is "created", roll the paper up above the water. Then move the roll of paper to some type of Anodizing tank and unroll it to coat the paper. I think this may be an excellent Robotics application. I am figuring the chemicals used here would be immediately lethal, but it could clean your carpet nicely.
Pvt Parts was quoted "Yeah they're crap for camouflage and look fucking stupid, that and some joker keeps writing "I luv the cock" and sticking it on my back, but man do they stop the bullets."
Also in the news FBI has arrested three men with suspected terrorist links in an Office Depot this morning, trying to buy three pallets of inkjet paper without having proper I.D. nor the required Federal permits to make the purchase.
Does this mean that paper beats rock AND scissors now?
Reading code is like reading the dictionary - you have to read half of it before you can go back and understand it.
... You can't really clog paper, can you?
The tensile strength is about 140 MPa according to TFA. This is similar to brass and far below carbon nanotubes at 63 GPa. http://en.wikipedia.org/wiki/Tensile_strength

Carbon fiber is a floppy woven cloth that can be cut with scissors, but that doesn't stop people from building planes, cayaks, and golf club shafts with the stuff by making a composite with epoxy.
Carbon fiber is great stuff- its main failing is that nobody can make the stuff fast enough (or manufacturers are intentionally not ramping up capacity to milk the aerospace/defense industry.) Boeing and the USAF are buying the stuff by the football field for their planes.
Please help metamoderate.
I am much more interested in the story concerning paper not based on carbon.

This somehow reminds me of an episode of Gilligan's Island where they discover that some home-made pancake syrup also works as a pretty effective adhesive. Just as they were patching the SS Minnow back together, however, they found that the glue didn't work quite so well as hoped as the material would lose integrity after a certain amount of time. (The time seemed to be around 20 minutes not including commercials...)
Of course, if you didn't read the article, you would realize I am talking about the material's vulnerability to water. As the substance is created on the surface of water, it also loses its strength when exposed to water. So while it's less likely that your dog may have eaten your homework, it's more likely to get rained out.
That headline should read "... stronger than nanotube paper", not nanotubes. Why that's a good benchmark for strength, I have no idea. It's generally used as a filter. It's like saying cotton plants are stronger than trees because cotton paper is stronger than normal paper.
I wonder how many /.ers are too young to even know what you're talking about? :)
(Yeah, I know there are still places where it's used - probably.)

Trees claim prior art. News at 11.

Yeah, but one sneeze and it'll all come crashing (fluttering?) down.
isn't most real paper, carbon-based? You know...the stuff that comes from trees?
Cheap, disposable, puncture resistant gloves for short term handling of biohazardous materials, particularly used syringe needles. Those would better protect health care workers from things like hepatitis C. Latex protects against the virus, but needles go right through it. Hep C treatment is painful, nauseating, fatiguing, causes depression and rage outbursts, makes your hair fall out, is very expensive (alpha interferon + ribavirin; around US$10,000: http://www.hepnet.com/hepc/DDW99/HCVSGP/wong.html) and is depressingly ineffective against the primary genome of that virus that's found in the US. Since hep C usually has few symptoms if any outwardly until very advanced, infected health care workers can spread the disease unknowingly. One layer of this with latex coating would save some lives, not to mention a lot of money for treatment. That savings would make up for the development costs.

It's worth something as a collectible? That's not actually that far-fetched, any more. (My Mom has a manual typewriter that she keeps - as a conversation piece, mainly. I actually wrote a few papers on that beast when I was in elementary school.)

That there isn't talking about the graphite paper, it is talking about materials currently in use in a similar fashion to what this new graphite paper can be used for. What gives it away is that graphite paper is brand spanking new, and so is not employed in anything.
Another dead giveaway is that according to both of the articles, "graphite paper" is based on "graphite" and not exfoliated vermiculite or mica.
Read it again dude, maybe you'll understand it then.
Because now, I can officially say that,

For those interested, here's the news@nature article, as well as the original research paper. Here's a paste of the abstract:
Preparation and characterization of graphene oxide paper

Free-standing paper-like or foil-like materials are an integral part of our technological society. Their uses include protective layers, chemical filters, components of electrical batteries or supercapacitors, adhesive layers, electronic or optoelectronic components, and molecular storage1. Inorganic 'paper-like' materials based on nanoscale components such as exfoliated vermiculite or mica platelets have been intensively studied2, 3 and commercialized as protective coatings, high-temperature binders, dielectric barriers and gas-impermeable membranes4,5. Carbon-based flexible graphite foils5, 6, 7 composed of stacked platelets of expanded graphite have long been used8, 9 in packing and gasketing applications because of their chemical resistivity against most media, superior sealability over a wide temperature range, and impermeability to fluids. The discovery of carbon nanotubes brought about bucky paper10, which displays excellent mechanical and electrical properties that make it potentially suitable for fuel cell and structural composite applications11, 12, 13, 14. Here we report the preparation and characterization of graphene oxide paper, a free-standing carbon-based membrane material made by flow-directed assembly of individual graphene oxide sheets. This new material outperforms many other paper-like materials in stiffness and strength. Its combination of macroscopic flexibility and stiffness is a result of a unique interlocking-tile arrangement of the nanoscale graphene oxide sheets.
Would this be anything like.....oh say.....CARBON PAPER?

Is this any better than plain old graphite for electrical conductivity, and more like pure graphene? If so, it could be very useful in places that won't get wet (which would include most existing electrical applications). It would be more useful still if it cold be applied dry with something like a pencil, then the solvent (which could still be water) would be applied. This would make home-brewed printed circuit boards much simpler and much less hazardous to create. No more resist masks and acid dipping.

Under its coat of spray-on imitation rust and an artful bandaging of silver duct-tape, the geometry of the paper-cored, carbon-wrapped frame makes Chevette's thighs tremble. There's a little double zik as the particle-brakes let go, then she's up and on it.

"Also, says materials scientist Boris Yakobson of Rice University in Houston, Texas, because water is so common as either liquid as rain or vapor as humidity, it will likely affect graphene sheets exposed to the environment in the long run if the material can't be protected from water's effects."

Since there is (practically) no water on Mars, it would last longer there.
May be a reason why power plants will work towards cleanup their coal/natural gas? Nah.
I prefer the "u" in honour as it seems to be missing these days.
Nanotubes and other graphites were showing ability to transport electrons nicely. I wonder if this can be used to form flexible wiring as well? If so, this could change how we do mobos in a BIG way.
I prefer the "u" in honour as it seems to be missing these days.
Doesn't that kill its practicality in things like planes and automobiles? If it rains, then you could have a major catastrophe on your hands... I'm surprised you read that far and then stopped. From TFA: So, the next task is to find other molecules that can replace water in the fabrication process. That research challenge and others probably puts commercialization of the technology at least 5 or 10 years away, Ruoff says.

Ordinary paper doesn't stand up to exposure to water either.
But laminate it in a protective coating, like most people's birth certificates, and it will last a lifetime.
Carbon fibre is often used laminated with a resin, similar to fibreglass. The carbon fibre has the strength, the resin gives it the structure.
It sounds like the new carbon paper could do the same thing, but will be stronger and cheaper.

Although water is it's Achilles heel at the moment, there's no water in space, so this material could likely benefit the exterior surfaces of spacecraft or stations etc. immensely even in its current form.
...enough said, though I wouldn't want to risk a paper cut down there.
All the concerns aside about this being not quite up to carbon nanotube strength, and dissolving when exposed to water, it seems to me that there are still a number of applications for something like this -- e.g., replacing stamped steel car bodies with painted paper. It reduces weight, reduces cost, and is possibly recyclable.
I'm sure there are a number of other applications as well -- stiffeners for notebook computer shells springs to mind, where the "carbon paper" is inside the plastic shell (literally "inside", with the plastic being injection-molded around it).
That was really the point of TFA to begin with.
Pretty neat stuff.
but, does anyone know if they even teach cursive writing in school anymore. I hope not, because whenever I come across it, I have a lot of trouble reading it (everyone's style is so different).
So what, exactly, is the main element in regular paper?
Ok, so now we've an airplane made of this. What happens if it crashes and catches fire?
I kid, I kid. Obviously steel's vulnerability to water takes place on a vastly different scale of time and affect.
Still, it does suggest that if this graphene-oxide paper is sufficiently advantageous in some domain (as you say, probably NOT aerojets and automocars), then means could be found to protect it from moisture. Right of the top of my head, the idea of spacecraft comes to mind. I wonder how much moisture makes it up to a low-earth-orbit? I would think that none would, but that seems like the kind of assumption that could be disastrously wrong.
Anyone else thinking "spacecraft"? As I understand it, there's not much moisture in space. This graphene-oxide paper might not be a suitable hull material, but it could be very useful for internal structure.
I thought they could only grow them a few millimeters long and what passes for nanotubes is a polymer of the microtubes. Still very amazing material however.

It's got an interesting technique behind it, and is supposed to be better than bittorrent (though Bram strongly disagreed, without giving details, at a talk at Stanford a couple of years ago). Meanwhile, Bram hardly invented P2P -- he cut his chops at Mojonation, and gnutella existed two years before that. -Carl
Possibly not. The porosity of many plastics is simply amazing.
Several composite aircraft have had issues with aluminum corroding. The fittings were buried within the epoxy.
