Malaysia taps potential in graphene

PUTRAJAYA: Malaysia has jumped on the graphene bandwagon, by exploring the material’s downstream economic potential, which is expected to generate RM9 billion worth of revenue and create 9,000 jobs by 2020.

Graphene is lauded as the new wonder material of the century.

It is 200 times stronger than steel and is able to conduct electricity better than any known material, and can be applied in numerous industries.

Intense commercialisation of graphene-based technology is taking place now in developed countries.

The applications that are relevant to Malaysia are lithium-ion battery, battery anodes and ultracapacitors, rubber additives, nanofluids (drilling fluid and lubricants), conductive inks and plastic additives.

Performance Management and Delivery Unit (Pemandu) chief executive officer Datuk Seri Idris Jala said the graphene venture is part of Malaysia’s drive towards an innovation-based economy.

“We can’t depend only on a strong domestic-led economy as our population is small. We have to look beyond and the graphene venture is part of the government’s Economic Transformation Programme,” he said at the launch of the National Graphene Action Plan, here, yesterday.

The venture will be handled by Pemandu, Agensi Inovasi Malaysia and NanoMalaysia Bhd.

The agencies will work together with the private sector, research and development institutions and universities on graphene commercialisation.

FGV's UK graphene venture to start operation by year-end

JEMPOL: Felda Global Ventures Holdings Bhd’s (FGV) graphene plant in Cambridge, the United Kingdom, will be ready in October and production is expected to begin at the end of this year or early 2015, said chairman Tan Sri Mohd Isa Abdul Samad.

“We have set up a company for this (venture), in which FGV owns a 70% stake. We are collaborating with the Cambridge University.

“We have also signed memorandums of understanding with several companies for the sale of this material, involving an investment of £20mil,” he told reporters when met after a breaking of fast at the Tuanku Muhriz Mosque in Bandar Seri Jempol.

The function, organised by Yayasan Felda and the Jempol parliamentary office, was graced by the Yang Dipertuan Besar Tuanku Muhriz Tuanku Munawir and Tunku Ampuan Besar Tuanku Aishah Rohani Tengku Besar Mahmud.

Isa was responding to Minister in the Prime Minister’s Department Datuk Seri Idris Jala’s statement that the National Graphene Action Plan 2020 aimed to generate a potential revenue of RM9bil and create 9,000 jobs by 2020.

Isa, who is also Jempol MP, said Felda was venturing into graphene production due to good returns and the material’s high prices.

In October last year, Felda signed a deal with Cambridge Nanosystems Ltd (CNS) under which it provides the raw material (by-products from crude palm oil) while CNS provides the proprietary technology to produce carbon nanotubes and graphene.

The material, a single-atom thick layer of graphite first isolated in 2004, is described as the strongest, thinnest and most stretchable crystal as well as the best electrical conductor known to man, and holds great promise for replacing conventional semiconductor materials such as silicon.

In Malaysia, graphene nanomaterials could benefit the electronics and electrical, oil, gas and energy, as well as palm oil and rubber industries.

Malaysia set to become Asia’s largest producer of graphene materials

Malaysia is poised to become the largest producer of graphene materials in Asia once Felda Global Ventures Holdings Bhd (FGV) sets up a graphene plant in the country within two years.

FGV Executive Vice-President of Palm Downstream Cluster Datuk Zakaria Arshad said the RM15 million plant was expected to have a production capacity of nine kilogramme of graphene per day.

"The location of the plant has not been specifically identified, but it is expected to be located at one of FGV's mills," he told reporters at the Malaysian Investment Development Authority (Mida) seminar on Graphene in Kuala Lumpur today.

Graphene material would be used in the development of products in various industries encompassing aerospace, telecommunications, rubber, electronics, oil and gas and solar, he said.

Last year, FGV, in a joint venture effort with Cambridge Nanosystems, built a carbon nanotubes and graphene plant in the United Kingdom that produces between 50 and 100 tonnes of products a year to cater the European market.

"We need to create more demand for these products in the country and in order to do that, higher awareness on graphene technology, especially among Malaysian companies, need to be addressed.

"That is why FGV is collaborating with MIDA to create more awareness on graphene technology," he said.

The half-day seminar drew more than 150 participants, mainly from companies that are keen to explore potential investments in products using graphene.

Mida Deputy Chief Executive Officer Datuk N. Rajendran said through the seminar, participants were encouraged to explore new areas in grapheme technology for the production of high quality products.

He said the size of the global graphene market was expected to increase by 2020, with the consequent maturation of graphene industrialisation.

"Graphene could generate substantial upside for Malaysia through the commercialisation of graphene-enhanced products if we leverage its full potential," said Rajendran.

He said in line with the National Graphene Action Plan 2020, Mida was committed to promoting the economic development of the graphene ecosystem, particularly in advanced materials. – Bernama, April 10, 2015.

Graphene

Right now, the supermaterial getting people excited is graphene.

This is the thinnest material on Earth that we've been able to create. A single layer of graphene has the thickness of one atom. But it's also the strongest material (by weight) ever measured. Depending on its purity, graphene is 40 to 100 times stronger than steel… and obviously weighs much less.

Last July, tech giant IBM announced it would invest $3 billion over the next five years to figure out how to use graphene to make semiconductors. IBM wants to use graphene to make transistors that will make computer chips 1,000 times faster and more energy-efficient than the current silicon-based ones.

So… why isn't everything made of graphene yet? Well, for one, nobody has figured out how to make large sheets of it yet. Right now, it costs $500 to produce a single gram. Meanwhile, a kilogram of aerospace aluminum costs $10. (That's $500,000 worth of graphene.)

Of course, getting the cost down was an issue for plastic in its early days, too. Research firm Allied Market Research estimates that the graphene market will reach nearly $150 million by 2020. That would reflect a growth rate of 44% within the next five years.

But those estimates are based on the current cost of making graphene. When the cost goes down, the use of graphene will explode and make it a market worth billions of dollars.

The fuss about graphene

BY WEIGHT, it is 100 times stronger than steel, yet it can stretch by as much as a quarter of its length. Graphene is the thinnest solid ever known, indeed the thinnest possible: it is a sheet of linked carbon atoms just one atom thick.

It is a great conductor of electricity and nearly transparent to visible light, but is impermeable to gases and liquids. It has so many surprising properties that it has been dubbed a "wonder material" and has earned its discoverers a Nobel prize.

Graphene-related patents have shot up from 3,018 in 2011 to 8,416 in 2014, the year the European Union launched a ten-year, billion-euro project to unravel the wonder material's mysteries. Why does graphene stir such interest?

The fuss began in 2003 when Andre Geim and his student Konstantin Novoselov, physicists at the Manchester University, first peeled layers of the stuff from graphite using sticky tape. Atom-thick sheets were thought so unlikely to be stable that the pair's report was rejected, twice, by the journal Nature. Once the Manchester pair was proved right, a flurry of studies began to measure the properties of the stuff.

Graphene was found to be incredibly strong, and electric current zipped across it with virtually no loss, up to 200-times faster than in silicon—not far off the speed of light. The material's strength was soon touted in graphene-enhanced sports kit such as tennis racquets and skis.

Graphene is not good at controlling or switching electric current, so making faster computers with it remains tricky. But applications such as touchscreens exploit its conductive nature. The material has found its way into better, lighter batteries and, in a few months' time, the first graphene light bulb will go on sale.

Can the "wonder material" live up to all the hype?

Plenty of research is going into joining other atoms to the graphene lattice, to make it do what electrical engineers would like. The material could help with water purification and desalination efforts; thin graphene sheets with holes just large enough for water molecules could sequester pollutants, while thin tubes lined with it could draw up water and leave salt behind.

Its pliable nature makes it suitable for wearable electronics with flexible displays—or even transparent ones. Pairs of electrons moving through graphene can be made to split up, making for "entangled states" that physicists would like to put to use in so-called quantum computers.

There are biological applications, too; a team at the Michigan Technological University is experimenting with a graphene-bound polymer that regenerates nerve cells in patients with spinal-cord injuries. Even birth control could be improved by graphene's strength and impermeability to liquids; in 2013, the Gates Foundation put $100,000 into an effort to develop a graphene-enhanced condom.

Ideas for using graphene are proliferating almost at the speed at which electrons move within it. Detractors insist that interest in the material is a bubble bound to burst, and that claiming graphene as an ingredient in a product is more about marketing than innovation.

But naysayers would do well to remember the history of silicon, which was purified a full century before it found much use; now it is the centrepiece of the global electronics industry. An understanding of what graphene is capable of, and how to make lots of it, has bloomed in far less time. If even a fraction of the applications envisaged for it take off, graphene will have earned its nickname as a wonder material.
