Industrial scale production of graphene

I am pleased to announce that the U.S. Patent and Trademark Office has recently granted a patent for my invention. After years of research, Canada Graphene can now develop industrial scale production of graphene.

– Mr. H. Famenini

Why is graphene so important?

Graphene is the “miracle material” which will make the next revolution in the High-Tech Industry possible.

Graphene has exceptional properties which makes it an ideal substance in the manufacturing of the next generation of Integrated Circuits (ICs), namely: graphene-based Integrated Circuit (ICs), hence, the next revolution.

In fact, graphene-based IC is the essential component of the next generation of electronic devices.

The silicone-based ICs have now reached their limits, and, the High-Tech Industry would like to replace them with the superior graphene-based ICs; however, they require an abundant and inexpensive supply of graphene in order to do so.

The market for graphene: Graphene-based ICs are destined to replace the silicone-based ICs in an endless list of devices such as mobile phones, tablets, computers, “household” appliances such as TV sets, washing machines, refrigerators, microwave ovens, etc. In short, graphene-based ICs are the essential component of virtually all of the next generation of electronic and electrical devices.

A brief explanation of the invention: The technology used for my invention comprises of three steps:

1. Producing a compact monolayer (a Langmuir monolayer).

2. Mounting/transferring the said monolayer onto a substrate.

3. Controlled conversion of the said monolayer to a graphene sheet.

The video below demonstrates the continuous production of a patterned compact monolayer (using a modified Langmuir–Blodgett trough).

A couple of notes about the video:

  1. The compact monolayer is produced by dropping a tiny droplet of a suitable organic material (represented by a tiny droplet of olive oil) onto the surface of a body of water.
  2. The microscopic-sized patterns are produced by a low-intensity laser beam. The laser beam evaporates the “unwanted” portions of the monolayer, leaving behind a monolayer with the desired patterns (nano-scale patterns).
  3. The patterned monolayer, which is blackened in the video, is then converted to a sheet of patterned graphene.

Solar panels:

The animation below demonstrates how my technology allows the construction of new and revolutionary “multi-layered” solar panels.

Placing multiple sheets of transparent solar panels over each other enables us to reduce the cost of production and maintenance (for equal performance) and reduce the overall surface area required (i.e. one  “multi-layered” solar panel will replace multiples of the conventional solar panels).

What next?

All the preliminary scientific works (and proof of concept) have been completed and a U.S. Patent has been issued to me for this revolutionary technology.

My next step is embarking on the final phase of my project, which is, bringing my technology to the market and ensuring the availability of massive amounts of graphene for use by the (High-Tech) industry.

All roads lead to Rome:

Canada Graphene is the only technology available to date which allows mass production of graphene sheets inexpensively.

Competitors: As of now, there is only one company in Europe which is capable of producing large graphene sheets (200 x 90mm), selling each sheet for $1500 (USD) while my technology can mass produce much larger graphene sheets costing less than $20 to produce.

Graphene samples are sold on the internet every day, so what is wrong with those graphenes?

The graphenes in the market suffer from two major problems, making them unsuitable for the High-tech Industry:

1) Size: The graphenes currently sold (e.g. on the internet) are graphene flakes and not graphene sheets (i.e. the graphene flakes are too small to be used by the High-Tech Industry; they are only useful for e.g. experiments in the laboratory).

2) Price: Currently available larger sized graphenes on the market are prohibitively expensive.

My technology solves the above drawbacks.

Does your (graphene-based) technology result in producing devices which are less expensive than the currently available (silicone-chips based) devices?

Yes; the final products (devices) will be less expensive than the currently available (silicone-chips based) devices, because:

  1. The starting material I use in my technology is different – I use inexpensive organic material  to produce graphene (which are used in making graphene-based ICs), whereas those same devices currently use the more expensive pure Silicone (to make silicone-based ICs).
  2. My method does not need a “particle-free room”, versus the present methods which do – Particle-free rooms are very expensive to set up and expensive to operate.

Furthermore, my technology will produce graphene (and graphene-based ICs) in the same existing plants which currently produce silicone-based ICs i.e. there is no need for new equipments; in fact we can do away with the “clean rooms” which are currently used by the industry.

Are your graphene-based products superior to the conventional silicone-based products? Is there an actual proof?

Yes and yes.

As for the proof, in Feb. 2010, I.B.M. Corporation produced graphene-based Integrated Circuits which operated 10 times faster than the silicone-based Integrated Circuits – these Integrated Circuits also used significantly less (battery) power, and, did not generate heat while in operation.

The I.B.M. researchers painstakingly isolated a small amount of graphene samples in their laboratory in order to produce their graphene-based ICs (IBM has not yet been able to mass produce graphene sheets).

Using my technology, manufacturing such faster graphene-based ICs will be even cheaper than manufacturing the silicone-based equivalents.

Has your invention been published in any scientific publications?

Yes, my invention was published in the European magazine, “Science and Technology”.
