Extremely small flakes of Graphene have been made into printing inks which can pattern thin plastic sheets as well as paper. The flakes are derived in an industrial process from high quality graphite particles in a process known as exfoliation. After the printing process the graphene flakes are organised in a loose arrangement and the contact area between graphene flakes is small. We are developing a conversion process to compress selected areas of the printed graphene regions to enhance heat transfer properties and at the same time make it more efficient when transferring electrical current for integrated electronic and optoelectronic components. Our first demonstration will be flexible sheets of micro LEDs and will lead to completely new and novel formats of solid state lighting and indicator devices. Further development may allow everyday packages to be smart and able to capture data which becomes incorporated in to the internet of things. Other applications would be wearable displays, point of care diagnostic strips, touch devices for light weight vehicles as examples.
