Innovation and Impact

Our research on 2D materials at Exeter has gained recognition beyond the academic community in various areas.

We are constantly exploring the commercial potential of emergent research conducted by our group at the University of Exeter.  This research has the capacity to reduce the cost and radically enhance the electrical, optical and mechanical properties of a wide range of products spanning a broad spectrum of industrial activity.

Various members of our team are exploring business cases for solutions that include; Patented conductive films that overcome the limitations of other materials; Conductive inks that meet the demands of the emerging flexible electronics industry; Nano Additives that can enhance the physical properties of composite materials.

 

Nanoengineered building materials

In the field of nanoengineered building materials, our group has developed a new graphene/concrete composite with an unprecedented range of enhanced and multifunctional properties compared to standard concrete Managing the environmental impact of mankind is a major challenge which sees the concrete industry being one of the main key contributor to the global greenhouse emissions. In addition, the urbanization of areas subject to major environmental risks, e.g. flooding and earth quakes, poses strict demands on resilient construction materials, which should ideally be easily accessible.  Our research on graphene reinforced concrete underpins all these key aspects.

Concrene Limited is a spin-off company from the University of Exeter, that introduces an innovative and patented type of concrete to the construction industry. For more details please see:  https://www.concrene.com/
