Graphene is the world's new wonder material. It's the thinnest electronic material ever invented, consisting of a layer of carbon atoms just a single atom thick -- the atoms are arranged in a hexagonal pattern. It weighs almost nothing, coming in at only 0.77 grams for a square meter.

But it's no lightweight. Graphene is 100 times stronger than steel of the same thickness. It conducts both heat and electricity better than copper, and has outstanding optical and mechanical properties. If it could be produced on an industrial scale, graphene might revolutionize fields such as electronics and even body armor.Graphene repels water and is highly conductive, a combination that keeps steel from coming into contact with water and slows down the electrochemical reactions that oxidize iron
Buffalo chemists designed a polymer coating containing this exotic form of carbon. They painted steel with the coating and then dipped the coated metal in a brine to see if it would stay rust-free. It did -- for an entire month. Such a coating could eliminate rusted cars forever.

Graphene could change that. It can be etched with a laser to create more surface area and in turn allow a capacitor to store way more energy than its ordinary carbon brethren. Capacitors can also go through many more cycles than batteries without failing. In the future, graphene supercapacitors could power electronics and even electric cars.Graphene oxide is remarkably good at absorbing radioactive waste. Researchers at Rice University and Lomonosov Moscow State University found that microscopic bits of graphene oxide bind to radioactive contaminants, turning them into clumps that can be easily collected.

Flexible Electronic Circuits
Silicon semiconductor chips give computers
their brainpower. They process the 1s and 0s of binary code that are the
fundamental building blocks of digital information. But graphene has the
potential to process those 1s and 0s much faster than silicon because it
conducts electricity better, all while using less power and generating less
heat. That means a laptop could operate 50 times faster and need no cooling
fans. Over the last two years giants such as IBM have developed working graphene-based processors for wireless
devices, and one company, Digital Core Design of Poland, announced in April
that it built a processor that could work in a tablet. The first graphene
processors could be reaching consumers in the next five years, as manufacturers
refine the fabrication process.
Sheets of graphene can crumple up like paper, but they are
difficult to flatten out. At Duke University scientists recently
attached graphene to a pre-stretched rubber sheet and found
that when the sheet was relaxed, the graphene still adhered to the
rubber even though it was crumpled up. That led them to layer the
graphene with polymer, which expanded and contracted when a current was
run through it – a key component in building artificial muscle.

Graphene foam can pick up small concentrations of the nitrates and ammonia found in explosives. A sensor developed at Rensselaer Polytechnic Institute the size of a postage stamp could one day be a regular part of the kit carried by bomb squads.
Australian researchers found a way to make fibers from a composite material made of (http://media.uow.edu.au/news/UOW118285.html) graphene that's stronger than Kevlar. Adding an equal amount of graphene and carbon nanotubes to a polymer produced a super-strong fiber that could be spun into the fabric used to make bulletproof vests. The fibers could also be used to strengthen other materials.
Photodetectors are computer chips that convert photons from
light into electrical signals. Every digital camera has one and they are
made of silicon. Frank Koppens and his colleagues at the Institute of
Photonic Sciences in Barcelona dotted a layer of graphene with lead
sulfide and created an ultra-sensitive and flexible photodector that
could lead to thinner cameras and more lightweight night vision goggles.

I wonder when this is going to make an impact on society, or will patent wars slow the implementation of this wonder material, it is rust resistant as well so marine applications?
