Researchers from Advanced Material Development (AMD) and the University of Sussex have announced what they refer to as "a major enhancement" in their carbon nanomaterial-based inks, reaching conductivity levels of 3,000,000 Sm-¹, approaching the performance of incumbent metal-based solutions.
With years of experience with graphitic inks, that previously achieved industry-best conductivity of 500,000 Sm-¹ (several times more conductive than other non-metal inks) - the latest breakthrough seems to significantly raise the bar.
Commenting on the potential of this achievement, John Lee, CEO of AMD, stated: "This is essentially the quantum shift in capability that those in the “graphene” space have long awaited. By enhancing the conductivity of our inks six-fold, we can now offer a viable alternative to traditional metal-based components in electronics, enabling the production of devices that are both high performing, robust and environmentally friendly. For example, recyclable and compostable electronic solutions could easily replace metals in RFID antennas, serving industries such as food packaging, where the presence of metal is unacceptable, and apparel, where cost and sustainable solutions are key."
Professor Alan Dalton, Professor of Materials Physics and Chief Scientific Advisor to AMD, commented: "The UK has always been at the forefront of scientific research and technological innovation. For over five years, our graphitic inks have led the market in conductivity, enabling the development of novel technologies in areas such as recyclable electronics and robust thin coatings for applications including EM Shielding where this development will bring true benefits for customers."
