4 What is Graphene? An Allotrope of Carbon Diamond Graphite Graphite is simply many stacked layers of graphene. 1980s C60 Buckyballs 1990s Carbon Nanotubes 2000s Graphene

5 What is Graphene? Graphene is two dimensional (2D) carbon, and it displays many unique and interesting properties. It s often called a wonder material. Strongest material known 5x more than steel But stretchable & flexible And very thin & transparent Just 1 atom thick (0.34nm) High electrical conductivity Much higher than silicon High thermal conductivity Excellent gas barrier Even helium can t pass

6 Example Application: Smart Glass Smart glass can be electrically controlled to switch between an on/off state. In the off state, the window becomes opaque adding privacy and blocking heat.

44 Summary We know from experience that when we add graphene to just about any target material we can see enhancement of mechanical, electrical, thermal and barrier properties. Haydale s plasma process can aid in the dispersion of graphene into many different materials. Graphene can enhance the conductivity of carbon-based inks, potentially enabling a replacement for more expensive silver inks. Target applications for Haydale include blood glucose sensors and pressure sensors (strain gauges), but our inks are suitable for any application where large amounts of silver ink are currently consumed.
