New graphene based material leads to flexible screens

The new material has been dubbed #GraphExeter. Like #graphene it is lightweight, strong, transparent and a good conductor of electricity. It differs from graphene in terms of not being composed of ‘pure’ graphene molecules.

@GraphExeter was created by placing molecules of ferric chloride tightly between two graphene layers produces a new system that is more than a thousand times a better conductor of electricity than graphene.

The focus of the application is with large, flat and flexible lighting. The main advantage is that the material is capable of high luminosity, beating comparable products by 50 percent greater brightness. This should aid the next generation of flexible screens. One limitation with the current developments in flexible screens is that the brightness that can be achieved decreases as the screen becomes larger. GraphExeter overcomes this.

Moreover, the lights are not only brighter, they are very resilient and they can be folded multiple, times without loss of functionality.

Further details are revealed in this University of Exeter video:

Researchers from the University of Exeter have pioneered an innovative new technique to make flexible screens more effective and efficient.A team of Engineers and Physicists from Exeter have discovered that #GraphExeter #graphene - a material adapted from the 'wonder material' graphene - can substantially improve the effectiveness of large, flat, flexible lighting.By using GraphExeter, the most transparent, lightweight and flexible material for conducting electricity, instead of pure graphene, the team have increased the brightness of flexible lights by up to almost 50 per cent.The research has also shown that using GraphExeter makes the lights 30 per cent more efficient than existing examples of flexible lighting, which are based on state-of-the-art commercial polymers.The research team believe the breakthrough could help significantly improve the viability of the next generation of flexible screens, which could be used for display screens, smartphones, wearable electronic devices, such as clothing containing computers or MP3 players.
