Archer Exploration, in collaboration with The University of Adelaide, has developed graphene-based conductive inks derived from Archer’s Campoona graphite deposit. The inks produced were used to print electronic circuits with an inkjet printer, later using a laser-scribed printer for the preparation of basic electrode patterns.

The graphene inks were reportedly prepared using a combination of established methods and proprietary methods that took advantage of the superior physical and chemical properties of Archer’s Campoona graphite. The rheological properties of inks are yet to be tested and optimized, and are the subject of the ongoing collaboration. The Company stated that the results of the work will be used to secure intellectual property rights to commercially viable technology integrating printed graphene componentry for biosensing devices.

Archer's CEO, Dr. Mohammad Choucair, commented on the success of the research: “The work with The University of Adelaide Graphene Hub highlights our continued and successful collaborative efforts in executing our advanced materials and technology strategy, and provides Archer with commercial opportunities to develop high-value graphene products and technologies in the focus area of human health, to underpin further development of our Campoona graphite resource.”
