A team of researchers based at The University of Manchester have found a low cost method for producing graphene printed electronics, which significantly speeds up and reduces the cost of conductive graphene inks.

Printed electronics offer a breakthrough in the penetration of information technology into everyday life. The possibility of printing electronic circuits will further promote the spread of the ‘Internet of Things’ (IoT) applications.

The development of printed conductive inks for electronic applications has grown rapidly, widening applications in transistors, sensors, antennas RFID tags and wearable electronics.

Current conductive inks traditionally use metal nanoparticles for their high electrical conductivity. However, these materials can be expensive or easily oxidised, making them far from ideal for low-cost IoT applications.

The team have found that using a material called dihydrolevogucosenone known as Cyrene is not only non-toxic but is environmentally– friendly and sustainable but can also provide higher concentrations and conductivity of graphene ink.

The National Physical Laboratory (NPL), who was involved in measurements for this work, has partnered with the National Graphene Institute at The University of Manchester to provide a materials characterisation service to provide the missing link for the industrialisation of graphene and 2D materials.

They have also published a joint NPL and NGI a good practice guide which aims to tackle the ambiguity surrounding how to measure graphene’s characteristics.

Graphene has the potential to create the next generation of electronics currently limited to science fiction: faster transistors, semiconductors, bendable phones and flexible wearable electronics.
