New graphene-based material could revolutionize electronics industry

April 30, 2012
The most transparent, lightweight and flexible material ever for conducting electricity has been invented by a team from the University of Exeter. Called GraphExeter, the material could revolutionise the creation of wearable electronic devices, such as clothing containing computers, phones and MP3 players.

GraphExeter could also be used for the creation of 'smart' mirrors or windows, with computerised interactive features. Since this material is also transparent over a wide light spectrum, it could enhance by more than 30% the efficiency of solar panels.

Adapted from graphene, GraphExeter is much more flexible than indium tin oxide (ITO), the main conductive material currently used in electronics. ITO is becoming increasingly expensive and is a finite resource, expected to run out in 2017.

These research findings are published in the journal Advanced Materials, a leading journal in materials science.

At just one-atom-thick, graphene is the thinnest substance capable of conducting electricity. It is very flexible and is one of the strongest known materials. The race has been on for scientists and engineers to adapt graphene for flexible electronics. This has been a challenge because of its sheet resistance, which limits its conductivity. Until now, no-one has been able to produce a viable alternative to ITO.

To create GraphExeter, the Exeter team sandwiched molecules of ferric chloride between two layers of graphene. Ferric chloride enhances the electrical conductivity of graphene, without affecting the material's transparency.

The material was produced by a team from the University of Exeter's Centre for Graphene Science. The research team is now developing a spray-on version of GraphExeter, which could be applied straight onto fabrics, mirrors and windows.

Lead researcher, University of Exeter engineer Dr Monica Craciun said: "GraphExeter could revolutionise the electronics industry. It outperforms any other carbon-based transparent conductor used in electronics and could be used for a range of applications, from solar panels to 'smart' teeshirts. We are very excited about the potential of this material and look forward to seeing where it can take the electronics industry in the future."

The Centre for Graphene Science brings together the Universities of Exeter and Bath in internationally-leading research in graphene. The Centre is bridging the gap between the scientific development and industrial application of this revolutionary new technology.

This research was funded by the EPSRC and Royal Society.

Graphene: Fundamentals and emergent applications

Graphene: Fundamentals and emergent applications
by Jamie H. Warner (Author), Franziska Schaffel (Author), Mark Rummeli (Author), Alicja Bachmatiuk (Author)


Providing fundamental knowledge necessary to understand graphene's atomic structure, band-structure, unique properties and an overview of groundbreaking current and emergent applications, this new handbook is essential reading for materials scientists, chemists and physicists. Since the 2010 physics Nobel Prize awarded to Geim and Novosolev for their groundbreaking work isolating graphene from bulk graphite, there has been a huge surge in interest in the area. This has led to a large number of news books on graphene. However, for such a vast inflow of new entrants, the current literature is surprisingly slight, focusing exclusively on current research or books on previous "hot topic" allotropes of carbon. This book covers fundamental groundwork of the structure, property,...

Graphene: A New Paradigm in Condensed Matter and Device Physics

Graphene: A New Paradigm in Condensed Matter and Device Physics
by E. L. Wolf (Author)


The book is an introduction to the science and possible applications of Graphene, the first one-atom-thick crystalline form of matter. Discovered in 2004 by now Nobelists Geim and Novoselov, the single layer of graphite, a hexagonal network of carbon atoms, has astonishing electrical and mechanical properties. It supports the highest electrical current density of any material, far exceeding metals copper and silver. Its absolute minimum thickness, 0.34 nanometers, provides an inherent advantage in possible forms of digital electronics past the era of Moore's Law.

The book describes the unusual physics of the material, that it offers linear rather than parabolic energy bands. The Dirac-like electron energy bands lead to high constant carrier speed, similar to light photons. The...
